Abstract:
This study investigates the performance of pencil graphite (PG) electrodes to identify the grade of pencil most suitable as bioanode for enzymatic glucose biofuel cell. Pencils of H, 3H, 5H and B grades are selected for this study. The surfaces of different grade PGs are modified with carboxylic acid functionalized multi walled carbon nanotubes (COOH-MW­CNT/PG), followed by immobilization with glucose oxidase (GOx) to fabricate the respect­tive bioanodes (GOx/COOH-MWCNT/PG). Morphological and electrochemical characteri­zations are carried out using scanning electron microscopy, electrochemical impedance spectroscopy, cyclic voltammetry and energy dispersive X-ray spectroscopy. All tested PG electrodes exhibited positive results with variable response characteristics towards glucose oxidation reaction. B-grade PG bioanode is found to have the highest coverage of the deposited nanobiocomposite with the fastest electron transfer rate. The half-cell electrode assembly with this grade of PG recorded the highest current density of 4.25 mA cm-2 at physiological glucose conditions (5 mM glucose, pH 7.0). Enzymatic glucose biofuel cell assembled with B-grade PG bioanode and platinum cathode generated an open circuit potential of 149 mV and maximum power density of 0.789 µW cm−2 from 5 mM glucose at ambient conditions (25 ± 3◦C). The results obtained for B-grade PG bioanode are comparable to those of conventional carbon and glassy carbon electrodes, thus demonstrating its applicability to enzymatic glucose biofuel cells.

Abstract:
Fuel Cells are important forms of sustainable power generation and Biofuel Cells utilize the use of bio-compatible/biodegradable molecules as fuels. Glucose is an ideal candidate to serve this purpose. In this project, a Glucose Fuel Cell (GFC) has been fabricated using the nanomaterials developed in the lab. The skeletal system of this GFC is a three-layered structure; a Membrane Electrode Assembly (MEA) composed of carbon electrodes (anode and cathode) and a Poly Vinyl Alcohol/Poly Acrylic Acid (PVA/PAA) polymer electrolyte. Gold and Silver (Au and Ag) nanoparticles are utilized as catalyst on the anode and cathode respectively, which are prepared by the use of green chemistry practice. One of the GFC has been compacted under hot press and the other non-hot pressed. ,which led to different surface areas. For the validation of the GFC stacks, the glucose concentration was selected around biologically available levels, i.e at 400 mg/dL in both the cases. One trial on hot pressed membrane with 200 mg/dL of glucose is also studied. Short Circuit Current (SCC) and Open Circuit Voltage (OCV) were measured following which the voltages and currents were measured across load resistances. The Thermal Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) studies were carried out on the membrane while the electrodes were characterized by Scanning Electron Microscopy (SEM). UV-Vis studies were carried out on the Au and Ag nanoparticle suspension before and after impregnation of carbon cloth electrodes. Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) has been utilized to estimate the concentration and thus the number of nanoparticles adsorbed on the surface of the carbon cloth. The variations of output current with the thickness of the membranes were studied. The assembly containing the catalytic particles showed power levels ranging between 128.7 nW-332.2 nW in the glucose concentration of 400 mg/dL. Rigorous efforts are under process to scale down the power consumption of electronics to extremely low levels. GFCs could be used as power generators in such devices. The inexpensiveness of the fuel is a remarkable factor.

Abstract:
The development of enzymatic biosensors and enzymatic biofuel cells (EBFCs) has been a significant area of research for decades. Enzymatic catalysis can provide for specific, reliable sensing of target analytes as well as the continuous generation of power from physiologically present fuels. However, the broad implementation of enzyme-based devices is still limited by low operational/storage stabilities and insufficient power densities. Approaches to improving upon these limitations have focused on the optimization of enzyme activity and electron transfer kinetics at enzyme-functionalized electrodes. Currently, such optimization can be performed through enzyme structural engineering, improvement of enzyme immobilization methodologies, and fabrication of advantageous electrode materials to enhance retained enzyme activity density at the electrode surface and electron transfer rates between enzymes and an electrode. In this work, varying electrode materials were studied to produce an increased understanding on the impacts of material properties on resulting biochemical, and electrochemical performances upon enzyme immobilization and an additional method of electroactive enzyme-based optimization was developed through the use of polymer-based protein engineering (PBPE). First, graphene/single-wall carbon nanotube cogels were studied as supports for membrane- and mediator-free EBFCs. The high available specific surface area and porosity of these materials allowed the rechargeable generation of a power density within one order of magnitude of the highest performing glucose-based EBFCs to date. Second, two additional carbon nanomaterial-based electrode materials were fabricated and examined as EBFC electrodes. Graphene-coated single-wall carbon nanotube gels and gold nanoparticle/multi-wall carbon nanotube-coated polyacrylonitrile fiber paddles were utilized as electroactive enzyme supports. The performance comparison of these three materials provided an increased understanding of the impact of material properties such as pore size, specific surface area and material surface curvature on enzyme biochemical and electrochemical characteristics upon immobilization. Third, PBPE techniques were applied to develop enzyme-redox polymer conjugates as a new platform for enzymatic biosensor and EBFC optimization. Poly(N-(3-dimethyl(ferrocenyl) methylammonium bromide)propyl acrylamide) (pFcAc) was grown directly from the surface of glucose oxidase (GOX) through atom-transfer radical polymerization. Utilization of the synthesized GOX-pFcAc conjugates led to a 24-fold increase in current generation efficiency and a 4-fold increase in EBFC power density compared to native GOX. GOX-pFcAc conjugates were further examined as working catalysts in carbon paper-based enzymatic biosensors, which provided reliable and selective glucose sensitivities and allowed a systematic analysis of sources of instability in enzyme-polymer conjugate-based biosensors and EBFCs. The knowledge gained through these studies and the in-depth characterization of an additional layer of optimization capacity using PBPE could potentially enhance the progress of enzymatic biosensor and EBFC development.

Abstract:
Ce mémoire est consacré à l’optimisation de la connexion enzymatique pour l’oxydation du glucose et la réduction du dioxygène dans une matrice de nanotubes de carbone (CNTs) sous forme de compression dans les biopiles à glucose, et à l’assemblage de biopiles dans un système à flux. Dans un premier temps, le transfert électronique indirect de la glucose oxydase (GOx) et de la glucose déshydrogénase FAD-dépendante (FADGDH) est optimisé dans une matrice nanostructurée de CNTs contenant différents médiateurs rédox. Ces bioanodes ont pu être combinées avec des biocathodes similaires à bases d’enzymes à cuivre, la laccase (Lac) et la bilirubine oxydase (BOD). La biopile GOx-NQ/Lac présente une puissance de l’ordre de 150 µW sous 150 mmol.L-1 de glucose et la biopile GOx-NQ/BOD orientée par la PP IX, quant à elle, possède une puissance de l’ordre de 0,5 mW sous 5 mmol.L-1 de glucose. Cette biopile présente une très bonne alternative à l’implantable ou à l’alimentation d’un appareil électronique à faible demande énergétique. La partie suivante concerne l’élaboration d’un design de biopile à flux optimisant la diffusion du substrat à l’intérieur de la bioélectrode. De ce fait, plusieurs systèmes de biopiles GOx-NQ/BOD à flux de substrat ont été étudiés. La configuration de flux traversant a permis d’obtenir une puissance de l’ordre de 1 mW sous 5 mmol.L-1 de glucose et oxygène dissous. La possibilité d’utiliser cette pile en décharge continue ou en cycle de charge/décharge a été étudiée. Ce système de biopile à flux de glucose a permis également d’associer plusieurs biopiles en série ou en parallèle. Ainsi, l’alimentation d’un minuteur et d’un test d’ovulation a pu être réalisée à l’aide de biopiles associées en série. D’autre part, l’utilisation d’un circuit de gestion de l’énergie a permis d’alimenter un capteur de température en stockant l’énergie produite par deux biopiles connectées en série. Cette partie se consacre également à une biopile basée sur l’association de la HRP à la cathode et la GOx-NQ à l’anode. Ce système est très intéressant puisque grâce à la maitrise du sens du flux de notre substrat, le peroxyde d’hydrogène formé par l’anode peut être alors consommé par la cathode. Cette pile s’est montrée parfaitement opérationnelle en condition physiologique et a abouti à l’obtention de puissances de l’ordre de 0,8 mW
This work is devoted to the optimization of the enzymatic connection for the oxidation of glucose and the reduction of dioxygen in a matrix of carbon nanotubes (CNTs) in the form of compression in glucose biofuel cells, and the assembly of biofuel cells in a flow system.First, mediated electron transfer of glucose oxidase (GOx) and FAD-dependent glucose dehydrogenase (FADGDH) is optimized in a nanostructured CNTs matrix containing different redox mediators. These bioanodes could be combined with similar biocathodes with copper enzyme bases, laccase (Lac) and bilirubin oxidase (BOD). The GOx-NQ/Lac biofuel cell has a power of the order of 150 μW under 150 mmol L-1 of glucose and the biofuel cell GOx-NQ/BOD oriented by the PP IX, order of 0.5 mW under 5 mmol L-1 of glucose. This biofuel cell presents a very good alternative to the implantable or to the supply of an electronic device with low energy demand.The next part concerns the development of a biofuel cell design with flux optimizing the diffusion of the substrate inside the bioelectrode. As a result, several GOx-NQ/BOD flow systems have been studied. The flow-through configuration made it possible to obtain a power of the order of 1 mW under 5 mmol L-1 of glucose and dissolved oxygen. The possibility of using this battery in continuous discharge or in charge/discharge cycle has been studied. This biofuel cell system with a glucose flow has also made it possible to associate several biofuel cells in series or in parallel. Thus, the power supply of a timer and an ovulation test could be realised using associated biofuel cells in series. The use of an energy management circuit made it possible to supply a temperature sensor by storing the energy produced by two biofuel cells connected in series.Moreover, this part is about another biofuel cell based on the association of HRP with the cathode and the GOx-NQ at the anode. This system is very interesting because, thanks to the control of the flow direction of our substrate, the hydrogen peroxide formed by the anode can then be consumed by the cathode. This stack was perfectly operational in physiological condition and led to the achievement of powers of the order of 0.8 mW

Abstract:
As biocélulas a combustível enzimáticas (BFCs) são dispositivos eletroquímicos que convertem energia química em energia elétrica, utilizando enzimas como biocatalisadores. Quando miniaturizada, uma BFC pode ser implantada em animais vertebrados e invertebrados, vislumbrando-se sua utilização na produção de energia elétrica para alimentar microdispositivos biomédicos e microssensores em pequenos insetos. No entanto, ainda é um desafio obter BFCs implantáveis e miniaturizadas, com uma potência suficiente (dezenas de microwatts) para alimentar microcircuitos eletrônicos de maneira estável e em longo prazo. Diante do exposto, esta tese de doutorado apresenta um estudo das propriedades eletroquímicas de eletrodos enzimáticos, visando a aplicação em BFCs de glicose/O2 miniaturizadas e implantáveis. Para isso, utilizaram-se fibras flexíveis de carbono (FCFs) modificadas com as enzimas bilirrubina oxidase (BOx) no cátodo e glicose desidrogenase (GDh) NAD-dependente no ânodo, a fim de se obter a redução de O2 e a oxidação de glicose, respectivamente. Os resultados obtidos mostram que FCFs previamente submetidas a um tratamento químico de oxidação com permanganato de potássio e com posterior eletrodepolimerização do mediador vermelho neutro produzem bioânodos estáveis e robustos. Estes eletrodos, combinados com biocátodos compostos por FCFs na ausência de mediadores redox, foram utilizados em BFCs miniaturizadas, que foram implantadas em formigas da espécie Atta sexdens rubrupilosa. A potência máxima da BFC operando in vivo foi 13,5 ± 3,8 µW cm-2 em 190 ± 58,9 mV, com corrente máxima de 143 ± 40,2 µA cm-2 e a voltagem de circuito aberto de 260 ± 99,6 mV. Acredita-se que estes valores ainda possam ser otimizados e este trabalho contribui para mostrar que a flexibilidade das FFC, a presença de um mediador de elétrons polimérico no ânodo, o uso do tratamento químico de oxidação com permanganato de potássio das fibras e a miniaturização dos eletrodos são elementos importantes, e que podem ser considerados no desenvolvimento de biocélulas a combustível implantáveis.
Enzymatic biofuel cells (BFCs) are electrochemical devices that convert chemical energy into electrical energy using enzymes as biocatalysts. When miniaturized, BFCs can be implanted in vertebrate and invertebrate animals and, their use to produce electrical energy to feed biomedical microdevices and micro-sensors in small insects can be observed. However, it is still challenging to obtain implantable and miniaturized BFCs, with sufficient power (tens of microwatts) to power electronic microcircuits in a stable and long-term manner. In view of the above, this PhD thesis presents a study of the electrochemical properties of enzymatic electrodes, aiming to use them in miniaturized and implantable glucose/O2 BFCs. In order to obtain a reduction in O2 and oxidation of glucose, flexible carbon fibers (FCFs) modified with bilirubin oxidase (BOx) enzymes in the cathode and glucose dehydrogenase (GDh) at the anode, respectively, were used. The results show that FCFs previously submitted to a chemical treatment of oxidation with potassium permanganate and, subsequently, electropolymerization of the neutral red mediator produce stable and robust bioanodes. These electrodes, combined with biocathodes consisting of FCFs in the absence of redox mediators, were used in miniaturized BFCs, which were implanted in Atta sexdens rubrupilosa ant species. The BFC maximum power source, operating in vivo, was 13.5 ± 3.8 μW cm-2 at 190 ± 58.9 mV, with a maximum current of 143 ± 40.2 μA cm-2 and the open circuit voltage was 260 ± 99.6 mV. Although these values can be optimized, this research shows that the flexibility of the FCF, the presence of a polymer electron mediator on the anode, using the chemical treatment of oxidation with potassium permanganate of the fibers and electrode miniaturization are important elements, which can be considered in the development of implantable biofuels.

Resumo: Neste trabalho foram desenvolvidos estudos visando o estabelecimento de um processo de produção de lipídeos microbianos a partir de fontes renováveis, particularmente xilose, carboidrato derivado do processo de hidrólise de bagaço de cana-de-açúcar. Foi utilizada a levedura oleaginosa Lipomyces starkeyi DSM 70296, previamente selecionada no Laboratório de Engenharia Bioquímica, Biorefino e Produtos de Origem Renovável (LEBBPOR). A partir dos resultados preliminares em frascos agitados, partiu-se para estudos de batelada alimentada em biorreator (1,3 a 3L). Foram estudadas diferentes estratégias de alimentação, sendo que em batelada alimentada repetida, foram encontradas as maiores concentrações de células (85,4 g/L) e de lipídeos (41,8 g/L). Posteriormente foram estudados modos de operação em processos contínuos em meio sintético e meio contento o hidrolisado hemicelulósico (H-H). As maiores produtividades de células (0,443 g/g) e de lipídeos (0,236 g/g) foram encontradas em cultivo contínuo a 0,03h-1. Na vazão específica de alimentação de 0,06 h-1 foram obtidas as maiores produtividades de células (0,600 g/L.h) e de lipídeos (0.288 g/L.h). Análises de cromatografia em fase gasosa dos diferentes cultivos feitos revelaram que os principais constituintes deste complexo são os ácidos graxos de cadeia longa, como o ácido palmítico (C16:0), ácido esteárico (C18:0), ácido oleico (C18:1) e ácido linoleico. Foi estimado o número de cetano em torno de 61, muito próximo do biodiesel de palma. Também foram feitos estudos de balanço de massa e de energia em cultivo batelada alimentada utilizando somente xilose como fonte de carbono. O valor de calor de combustão (Qc) de 25,7 kJ/g obtido após 142 h de cultivo representa aproximadamente 56% do conteúdo energético do óleo diesel (45,4 kJ/g), indicando o potencial da L. starkeyi para biodiesel. Cultivos contínuos subsequentes foram feitos para a compreensão do processo de acúmulo de lipídeos, utilizando a ferramenta estatística de reconciliação de dados para melhorar os dados experimentais obtidos em quimiostato, reduzindo os erros experimentais para posterior cálculo de análise de fluxos metabólicos (MFA). Nesse sentido, os lipídeos produzidos por L. starkeyi apresentam relevante importância do ponto de vista acadêmico e industrial, podendo ser utilizados como matéria-prima para biodiesel e indústria oleoquímica
Abstract: Studies attempting the establishment of a microbial lipid production process from renewable resources, mainly xylose, were developed. This pentose, obtained from sugar cane bagasse hydrolysis. The oleaginous yeast Lipomyces starkeyi DSM 70296, previously selected at the Laboratory of Biochemical Engineering, Biorefining and Products from Renewable Sources (LEBBPOR), was used throughout this thesis. After preliminary studies in shake flasks, we started fed-batch studies in fermentor (1.3 to 3L). Among the strategies studied, the highest cell mass and lipid concentrations reached up to 85.4 and 41.8 g/L, respectively, when repeated fed?batch strategy was applied. Subsequently, continuous processes were studied in synthetic medium and media containing hemicellulosic hydrolysate (H-H). The highest overall cell mass (0.443 g/g) and lipid yields (0.236 g/g) were achieved at dilution rate of 0.03 h-1. At dilution rate of 0.06 h-1, were obtained the highest productivities of cell mass (0.600 g/L.h) and lipids (0.288 g/L.h). Gas chromatography of esterified lipids revealed that the major constituents of this complex are long-chain fatty acids, such as palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), and linoleic acid (C18:2) with an estimated cetane (around 61) very close to the palm biodiesel. Also have been studies of mass and energy balances from fed-batch cultivation using xylose as sole carbon source. The combustion heat (Qc) value 25.7 (kJ/g) obtained after 142 h of fed-batch cultivation, represents approximately 56% of the energy content of diesel oil (45.4 kJ/g), indicating the potential of L. starkeyi for biodiesel. Continuous cultures were made subsequently to understanding the process of lipid accumulation using a statistical tool for data reconciliation was used to improve the experimental data obtained in chemostat culture reducing the experimental errors for subsequent calculation of metabolic flux analysis (MFA). In this sense, lipids produced by L. starkeyi have relevant importance of academic and industrial point of view, as feedstock for biodiesel and oleochemical industry applications

Abstract:
Le développement de générateurs d'énergie pour alimenter des micro-appareils électroniques implantés est devenu une option inéluctable. L'objectif général qui a orienté ces recherches était l'élaboration et les études approfondies des propriétés nanomatériaux métalliques utilisables comme électrocatalyseurs afin de convertir l'énergie chimique en énergie électrique. Les nanomatériaux sont obtenus par la méthode de synthèse : Bromide Anion Exchange (BAE) qui a été scrupuleusement revisitée puis optimisée avec un agent réducteur faible (AA) et fort (NaBH4). Cette voie de synthèse a permis d'obtenir (rendement ≥ 90 %) des matériaux plurimétalliques composés d'or, de platine et de palladium. Un prétraitement des supports commerciaux des nanoparticules a permis d’augmenter leurs surfaces, spécifique et active respectivement de 48 et 120 %. Les études (électro)analytiques ont permis d'identifier les intermédiaires et produits de réaction du combustible. Le glucose s'oxyde sans rupture de la liaison C-C pour donner majoritairement du gluconate avec une sélectivité ≥ 88 %. Les tests réalisés en biopile hybride (cathode enzymatique) indiquent que les catalyseurs Au/C-AA et Au60Pt40/C-NaBH4 sont les meilleures anodes abiotiques (Pmax = 125 µW·cm-2 à 0,4 V). Par ailleurs, les piles sans membrane séparatrice et sans enzyme ont été réalisées avec succès pour activer un stimulateur cardiaque et un système de transmission d'information en mode "Wifi". Ces dispositifs, rapportés pour la première fois, ouvrent une ère nouvelle pour la conception de convertisseurs d'énergie pour alimenter les implants médicaux ou des appareils sans fil de détection et de surveillance
The development of energy converters to power implanted micro-electronic devices has become a cornerstone item. The whole target which has governed this research was the design of advanced nanostructures metals used as electrocatalysts for converting chemical energy into electrical one. These nanomaterials were obtained by the synthesis method: Bromide Anion Exchange (BAE) that has been carefully revisited and optimized, using a weak reducing agent (AA) and strong one (NaBH4). It allowed to prepare efficiently various plurimetallic nanomaterials composed of gold, platinum and palladium (yield ≥ 90%). A thermal pretreatment of commercial carbon supports of nanoparticles has highly boosted their specific and active surface areas with a gain of 48 and 120%. Based on in situ and ex-situ (electro)analytical methods, the intermediates and final reaction products of the fuel oxidation were identified. Glucose electrooxidation occurs without C-C bond cleavage and gives predominantly gluconate with a selectivity ≥ 88 %. Results from the hybrid biofuel cell tests (with an enzyme as cathode catalyst) indicate that Au/C-AA and Au60Pt40/C-NaBH4 are the best abiotic anodes (Pmax = 125 µW cm-2 at 0.4 V cell voltage). A fuel cell without separating membrane and enzyme has been successfully constructed and used to activate a pacemaker and an information transmission system based on "wireless" mode. These last experiments, reported for the first time as using nanomaterials in membrane-less configuration, open a new approach in the design of advanced energy converters to power medical implants or remote systems for detection and electronic monitoring

Abstract:
Miniaturized glucose-oxygen biofuel cells are useful to power implantable medical devices such as biosensors. They are small, more biocompatible and run continuously on glucose and oxygen, providing cleaner energy at neutral environment. A typical glucose-oxygen biofuel cell consists of an anode with glucose oxidase (GOx) and a cathode with various oxygen reducing catalysts. This thesis describes experimental investigations of the major issues of such systems, viz.: complex electrode fabrication, enzyme instability and inefficient oxygen reduction. Electrodes were built using the simple and scaleable bulk modification method, where all the material was simply mixed and bound together into composites with epoxy resin. For the anodes, the composite made of 10% GOx with 7:7 TTF-TCNQ was found optimal. The GOx electrodes were modified with various enzyme stabilisers (PEI, DTT, PEG, GLC, FAD and mixture of PEI:DTT and PEI:FAD) and 2% of PEI-DTT (1:1 w/w) was most effective in the presence of O2. Its maximum output current density was 1.8 x 10-2 ± 9.9 x 10-3 A.m-2. It also showed the resistant against O2 electron deprivation and enzyme inhibition. Its KM.was 5 mM. For the cathodes, various oxygen reducing catalysts (metalised carbon, anthroquinone modified carbon, laccase and bilirubin oxidase) were incorporated into graphite composite and the electrodes were pretreated in different media in order to enhance their catalytic activity. None showed four-electron O2 reduction. NaOH-pretreated cobalt (II) salophen composite electrodes showed two-electron O2 reduction and were most catalytic. Its standard catalytic rate constant was 1.2 x 10-5 ± 1.2 x 10-6 m.s-1. Of the catalysts examined, metal complex composites gave the best results for oxygen-reducing cathodes and their pretreatment led to the synergetic effect because it increased the concentration of catalytic surface oxygen groups and enhanced oxygen reduction.

Abstract:
La première partie du travail présenté ici se concentre sur l’optimisation d’une cathode à oxygène. Tout d’abord, l’utilisation d’une nouvelle enzyme (la BOD de Magnaporthe oryzae) permet de multiplier le courant de réduction de l’oxygène en eau jusqu’à neuf fois. Ensuite la synthèse d’un polymère rédox adapté a permis d’améliorer le coefficient de diffusion des électrons dans l’hydrogel résultant en l’augmentation de la densité de courant générée. Enfin nous sommes passés d’uneélectrode de carbone en 2 dimensions à une fibre d’or poreuse tridimensionnelle. Après modification de cette fibre avec l’hydrogel rédox à base de BOD de M. oryzaenous avons évalué sa biocompatibilité : in vitro les tests ont montré l’absence totale de cytotoxicité et seule une très faible réponse inflammatoire ; in vivo aucune infection ne s’est déclarée pendant les 8 semaines d’implantation dans les souris etla formation d’une capsule fibrotique autour de l’électrode traduit sa bonne intégration dans les tissus de l’animal. La seconde partie concerne la biopile dans son intégralité, construite à partir de la cathode optimisée et d’une anode adaptée à base de GDH. Elle permet de générer jusqu’à 240 μW.cm-2 dans du tampon Pipes/CaCl2 à 5mM de glucose. La biopile a ensuite été testée dans du sang humain total. Un maximum de 129 μW.cm-2 a été obtenu dans un échantillon avec une glycémie de 8,2 mM sous air. De plus nous avons constaté que la densité de puissance délivrée augmente proportionnellement avec la glycémie des différents échantillons de sang testés, faisant de la biopile à la fois une source d’électricité et un biocapteur à glucose ce qui n’avait jamais été démontré auparavant
The first part of the work presented here focuses on the optimization of an oxygen cathode. First, the use of a new enzyme (BOD from Magnaporthe oryzae) permit to increase the current of reduction of oxygen into water by a factor nine. Then the synthesis of a suitable redox polymer greatly improved the diffusion coefficient of electrons in the hydrogel, resulting in an increase of the current density. Finally we switched from a two-dimensional carbon electrode to a three-dimensional porous gold fiber. After modification of the fiber with the redox hydrogel based on BOD from M. oryzae, we assessed its biocompatibility: in vitro the tests showed the total absence of cytotoxicity and only a very low inflammatory response; in vivo noinfection appeared during the 8 weeks of implantation in mice and the formation of afibrotic capsule around the device reflects its successful integration into the animal tissues.The second part concerns the full biofuel cell, elaborated from the optimized cathode and an adapted GDH-based anode. It could generate up to 240 μW.cm-2 at 5mMglucose in Pipes/CaCl2 buffer. The biofuel cell was then tested in whole human blood. A maximum of 129 μW.cm-2 was obtained in a sample with 8,2 mM glycaemiaunder air. In addition we observed that the delivered power density increased proportionally with the glycaemia of the different blood samples tested, making the biofuel cell both a power source and a glucose biosensor at the same time which had never been shown before

Abstract:
This paper investigates the proton diffusion phenomenon between the anode catalyst and the electrode in an enzymatic bio-fuel cell. The bio-fuel cell uses enzymatic organism as the catalyst instead of the traditional noble metal, like platinum. The fuel is normally the glucose solution. The fuel cell is membrane-less and produces electricity from the reaction taken place in the organism. When the biochemical reaction occurs, the protons and electrons are released in the solution. The electrons are collected by the electrode plate and are transported to the cathode through an external circuit, while the protons migrate to the cathode by the way of diffusion. Unfortunately, protons are easy to dissipate in the solution because the enzyme is immersed in the neutral electrolyte. It is an important issue of how to collect the protons effectively. In order to investigate the diffusion process of the protons, a molecular dynamics simulation technique was developed. The simulation results track the transfer motion of the protons near the anode. The diffusivity was evaluated from the trajectory. The research concludes that the higher the glucose concentration, the better the proton diffusivity. The enzyme promotes the electrochemical reaction; however, it also plays an obstacle in the proton diffusion path.

Abstract:
In biosensor design, sensor for blood-glucose-level detection is one of the elementary concepts. Many research groups have reported opto-electro-mechanical and biomimetic techniques for glucose sensing based on nanomaterials. (1) However, the popular commercialized techniques involve drawing blood samples and in-vitro processing. An implantable sensor requires energy source for operation with wire in-out provision for acquiring power and sending signals. Needless to say, the limitation for such a glucose sensor is alimentary rather than elementary. The problem requires innovative design to develop sustainable ensemble of bio-energy harvesting, sensing and telemetry components. The study, reported in this article, is directed towards developing a sensor-fuel cell technology with the potential of miniaturization for implants. The device design is a combination of nano-engineered composites and flexible thin film processing to achieve high density packaging. Of which, the end goal is simultaneous generation-transmission of sensory signals and production of energy.
