Resumen
We describe polymer-stabilized droplets capable of recognizing and picking up nanoparticles from substrates in experiments designed for transporting hydroxyapatite nanoparticles that represent the principal elemental composition of bone. Our experiments, which are inspired by cells that carry out materials transport in vivo, used oil-in-water droplets that traverse a nanoparticle-coated substrate driven by an imposed fluid flow. Nanoparticle capture is realized by interaction of the particles with chemical functionality embedded within the polymeric stabilizing layer on the droplets. Nanoparticle uptake efficiency is controlled by solution conditions and the extent of functionality available for contact with the nanoparticles. Moreover, in an elementary demonstration of nanoparticle transportation, particles retrieved initially from the substrate were later deposited “downstream,” illustrating a pickup and drop-off technique that represents a first step toward mimicking point-to-point transportation events conducted in living systems.

Resumen
The objective of the present study is development of novel surface-active block, comb-like, and branched copolymers with peroxide-containing chains, as well as derived functional luminescent and magnetic nanoparticles. The main experimental approaches are based on tailored synthesis of the oligoperoxide surfactants of desired structures and derived coordinating complexes of transitional and rare earth elements. Oligoperoxide-based synthesis of luminescent, magnetic, and other functional nanocomposites with controlled size distribution, functionality, reactivity, and biocompatibility is described. Developed methods provide combining the formation of polymeric, metal, and metal-oxide nanoparticles with irreversible modification of their surface by functional fragments capable of radical and other reactions, including binding of physiologically active substances. Novel nanoparticles were studied by chemical, colloidal-chemical, and rheological methods, X-ray diffraction technique, luminescent spectroscopy, and transmission and scanning electronic microscopy. The availability of ditertiary peroxide fragments on the nanoparticle surface provides a possibility of radical grafting functional polymer chains. The developed functional nanoparticles have been used for phagocytosis measurement, as well as markers of pathological cells, antimicrobial remedies, and nanocarriers for targeted drug delivery.

Resumen
During the past two decades, increasing research attention has been devoted to nanomaterials (materials in the range of 10-100 nm) because of their unique optoelectronic properties. In particular, inorganic nanomaterials, such as quantum dots, metal-based nanoparticles and silica nanoparticles, have been investigated extensively. Instead, nanomaterials based on organic molecules are been subject of research only since very recent years. This thesis presents an extensive study of novel fluorescent organic nanoparticles and fluorescent organic binary and ternary nanoassemblies. In particular the attention is focused on the preparation and characterization of organic nanoparticles and new nanocomposites obtained from different types of small organic chromophores, their stabilization and the use of these materials for biological and optoelectronics applications.

Resumen
Nanoparticle system research and characterization is the focal point of this research and dissertation. In the research presented here, magnetite, cobalt, and ferrite nanoparticle systems have been explored in regard to their magnetocaloric effect (MCE) properties, as well as for use in polymer composites. Both areas of study have potential applications across a wide variety of interdisciplinary fields. Magnetite nanoparticles have been successfully dispersed in a polymer. The surface chemistry of the magnetic nanoparticle proves critical to obtaining a homogenous and well separated high density dispersion in PMMA. Theoretical studies found in the literature have indicated that surface interface energy is a critical component in dispersion. Oleic acid is used to alter the surface of magnetite nanoparticles and successfully achieve good dispersion in a PMMA thin film. Polypyrrole is then coated onto the PMMA composite layer. The bilayer is characterized using cross-sectional TEM, cross-sectional SEM, magnetic characterization, and low frequency conductivity. The results show that the superparmagnetic properties of the as synthesized particles are maintained in the composite. With further study of the properties of these nanoparticles for real and functional uses, MCE is studied on a variety of magnetic nanoparticle systems. Magnetite, manganese zinc ferrite, and cobalt ferrite systems show significant broadening of the MCE and the ability to tune the peak temperature of MCE by varying the size of the nanoparticles. Four distinct systems are studied including cobalt, cobalt core silver shell nanoparticles, nickel ferrite, and ball milled zinc ferrite. The results demonstrate the importance of surface characteristics on MCE. Surface spin disorder appears to have a large influence on the low temperature magnetic and magnetocalorie characteristics of these nanoparticle systems.

Resumen
Cette thèse décrit le développement de nouvelles méthodes pour obtenir des nanoparticules fonctionnelles polyvalentes qui peuvent potentiellement être utilisées pour des applications biomédicales telles que la vectorisation de médicaments, des essais biologiques et la bio-imagerie. Les nanomatériaux sont des outils polyvalents qui ont trouvé des applications comme vecteurs de médicaments, la bio-imagerie ou les biocapteurs. En particulier, les nanoparticules de type core-shell ont attiré beaucoup d'attention en raison de leur petite taille, une relation surface/volume élevée, et une biocompatibilité. Dans ce contexte, nous proposons dans la première partie de la thèse (Chapitre 2), une nouvelle méthode pour obtenir des nanoparticules core-shell via la polymérisation radicalaire en émulsion et vivante combinées. Des particules cœurs de polystyrène de 30 à 40 nm, avec une distribution de taille étroite et portant à la surface des groupements iniferter ont été utilisés pour amorcer la polymérisation supplémentaire d'une couche de polymère. Des nanoparticules core-shell ont été préparées de cette façon. Différents types d’enveloppes : anionique, zwitterioniques, à empreintes moléculaires, thermosensibles, ont ainsi été greffées. Notre méthode est une plate-forme polyvalente permettant d'ajouter des fonctionnalités multiples soit dans le noyau et/ou l'enveloppe pour les études d'interaction cellulaire et de toxicité, ainsi que des matériaux récepteurs pour l'imagerie cellulaire. Dans la deuxième partie de la thèse (Chapitre 3), nous décrivons un procédé nouveau et polyvalent pour la modification de surface des nanoparticules de conversion ascendante (UCP). Ce sont des nanocristaux fluorescents dopés de lanthanides qui ont récemment attiré beaucoup d'attention. Leur fluorescence est excitée dans le proche infrarouge, ce qui les rend idéales comme marqueurs dans des applications biomédicales telles que les tests biologiques et la bio-imagerie, l'auto-fluorescence étant réduite par rapport à des colorants organiques et les quantum dots. Cependant, les UCP sont hydrophobes et non-compatible avec les milieux aqueux, donc une modification de leur surface est essentielle. La stratégie que nous proposons utilise l'émission UV ou visible après excitation en proche infrarouge des UCP, comme source de lumière secondaire pour la photopolymérisation localisée de couches minces hydrophiles autour les UCP. Notre méthode offre de grands avantages comme la facilité d'application et la fonctionnalisation de surface rapide pour fixer divers ligands, et fournit une plateforme pour préparer des UCP encapsulée de polymères pour des différentes applications. Des hydrogels stimuli-sensibles sont des matériaux qui changent leurs propriétés physicochimiques en réponse à des stimuli externes tels que la température, le pH ou la lumière. Ces matériaux intelligents jouent un rôle critique dans des applications biomédicales telles que la vectorisation de médicaments ou l'ingénierie tissulaire. La troisième partie de cette thèse (Chapitre 4) propose un nouveau procédé de préparation d'hydrogels photo et pH sensible. Deux composantes, l'un photosensible à base dl'acide 4-[(4-méthacryloyloxy) phénylazo] benzoïque et l'autre cationic contenant des unités 2-(diéthylamino)éthyl méthacrylate, ont été synthétisés. Leur association donne des particules monodispersées de 100 nm photo et pH sensibles. Ces nanoparticules peuvent être potentiellement utilisées pour la vectorisation de médicaments, en particulier de biomolécules telles que protéines ou siARN. En conclusion, nous avons conçu plusieurs nouvelles méthodes efficaces, polyvalentes, génériques et facilement applicables pour obtenir des nanoparticules et nanocomposites de polymères fonctionnels qui peuvent être appliqués dans de différents domaines biomédicaux comme la vectorisation de médicaments, les biocapteurs, les tests biologiques et la bio-imagerie
This thesis describes the development of novel methods to obtain versatile, functional nanoparticles that can potentially be used for biomedical applications such as drug delivery, bioassays and bioimaging. Nanomaterials are versatile tools that have found applications as drug carriers, bioimaging or biosensing. In particular, core-shell type nanoparticles have attracted much attention due to their small size, high surface to volume ratio and biocompatibility. In this regard, we propose in the first part of the thesis (Chapter 2), a novel method to obtain core-shell nanoparticles via combined radical emulsion and living polymerizations. Polystyrene core seeds of 30-40 nm, with a narrow size distribution and surface-bound iniferter moieties were used to further initiate polymerization of a polymer shell. Core-shell nanoparticles were prepared in this way. Different types of shells : anionic, zwitterionic, thermoresponsive or molecularly imprinted shells, were thus grafted. Our method is a versatile platform with the ability to add multi-functionalities in either the core for optical sensing or/and the shell for cell interaction and toxicity studies, as well as receptor materials for cell imaging. In the second part of the thesis (Chapter 3), we describe a novel and versatile method for surface modification of upconverting nanoparticles (UCPs). UCPs are lanthanide-doped fluorescent nanocrystals that have recently attracted much attention. Their fluorescence is excitated in the near infrared, which makes them ideal as labels in biomedical applications such as bioimaging and bioassays, since the autofluorescence background is minimized compared to organic dyes and quantum dots. However, UCPs are hydrophobic and non-compatible with aqueous media, therefore prior surface modification is essential. The strategy that we propose makes use oft he UV or Vis emission light of near-infrared photoexcited upconverting nanoparticles, as secondary light source for the localized photopolymerization of thin hydrophilic shells around the UCPs. Our method offers great advantages like ease of application and rapid surface functionalization for attaching various ligands and therefore can provide a platform to prepare polymeric-encapsulated UCPs for applications in bioassays, optical imaging and drug delivery. Stimuli responsive hydrogels are materials that can change their physico-chemical properties in response to external stimuli such as temperature, pH or light. These smart materials play critical roles in biomedical applications such as drug delivery or tissue engineering. The third part of the thesis (Chapter 4) proposes a novel method for obtaining photo and pH-responsive supramolecularly crosslinked hydrogels. Two building blocks, one containing photoresponsive 4-[(4-methacryloyloxy)phenylazo] benzoic acid and the other, consisting of cationic 2-(diethylamino)ethyl methacrylate units, were first synthesized. Combining the two building blocks yielded photo and pH responsive monodisperse 100-nm particles. These nanoparticles can be eventually utilized for drug delivery, especially delivery of biomolecules such as siRNAs or proteins. In conclusion, we have designed several new efficient, versatile, generic and easily applicable methods to obtain functionalized polymer nanoparticles and nanocomposites that can be applied in various biomedical domains like drug delivery, biosensing, bioassays and bioimaging

Resumen
Functional nanoparticles have garnered considerable attention due to their intriguing physical properties at the nanoscale for a broad range of applications, such as photocatalysis, capacitive energy storage, thermoelectric power generation, solar energy harvesting, flexible and transparent electronics, drug delivery, biomolecular electronics, and analytic chemistry, etc. Successful synthesis of nanoparticles and precise control over their shapes are critical to achieving desired functions. In the first part of my thesis, an effective synthetic route to plain nanoparticles is briefly introduced. Based on this general route, the synthesis of solid iron oxide nanoparticles and a slightly modified synthetic method of solid silica nanoparticles are presented in detail. In the second part of my thesis, simulation of optical absorption spectra and plasmonic near-field maps of gold nanoparticle and gold/titanium oxide nanoparticle are explored, and the effectiveness of simulation in predicting, optimizing, and guiding experimental design is emphasized.

Resumen
Les nanoparticules fonctionnalisées continuent de susciter beaucoup d’interêt dans les applications biomédicales et les essais biologiques. Elles sont devenues un élément clé dans la recherche en nanobiotechnologie. Un des axes primordiaux des travaux de recherche est le développement de stratégies polyvalentes de fonctionnalisation de surface pour différentes nanoparticules allant de nanostructures de diamants à des nanoparticules d'oxyde de fer, des particules de silice et des nanocapsules lipidiques. Un des objectifs en particulier a été l’introduction de diverses fonctionnalisations sur les mêmes nanoparticules en utilisant soit des ligands dérivés de la dopamine ou soit par chimie « click » de Cu(I) catalysé. Il en résulte des nanostructures bien dispersées fonctionnalisées avec différents ligands à leurs surfaces. Les applications de ces nanostructures pour l'inhibition des infections virales et pour la délivrance de gènes ont été étudiées. En effet, l'inhibition de l'entrée du VHC a été identifiée comme étant une stratégie thérapeutique potentielle. Il a pu être démontré que différentes nanoparticules peuvent être efficacement conçues pour afficher les propriétés de lectine et se comporter donc comme des inhibiteurs efficaces d'entrée du virus in vitro. Les pseudo-lectines étudiées ici comprennent les nanoparticules dérivées du fer, de silice, du diamant et des nanocapsules lipidiques comportant toutes des fragments d’acide boronique attachés à leurs surfaces.Par ailleurs, le potentiel des nanoparticules de diamant pour la délivrance de gènes a été étudié
Functionalized nanoparticles continue to attract interest in biomedical applications and bioassays and have become a key focus in nanobiotechnology research. One of the primal focuses of the research work was the development of versatile surface functionalization strategies for different nanoparticles ranging from diamond nanostructures to iron oxide nanoparticles, silica particles and lipid nanocapsules. One particular aim was the introduction of various functionalities onto the same nanoparticles using either dopamine-derived ligands or Cu(I) catalyzed “click” chemistry strategies. This resulted in well-dispersed nanostructures with different ligands present on the surface of the nanostructures. The possibilities to use such nanostructures for the inhibition of viral infections and for gene delivery were investigated. Indeed, inhibiting the entry of HCV has been identified as a potential therapeutic strategy. It could be demonstrated that various nanoparticles can be efficiently engineered to display “lectin-like” properties and indeed behave as effective viral entry inhibitors, in vitro. The pseudo-lectins investigated here include iron-, silica-, diamond-, (lipid nanocapsule)-derived nanoparticles all featuring surface-attached boronic acid moieties. In parallel to work on HCV entry inhibition, the potential of diamond nanoparticles as gene delivery system was investigated. Water dispersible and biocompatible polypegylated diamond particles were prepared using different dopamine ligands and their effect on gene delivery has been studied

Resumen
This thesis will focus on DFT for calculations of large metallic nanoparticles. It will show new algorithms that were developed for reduced scaling DFT methods for metals; the testing, verification and design of new descriptors for predicting the catalytic activity of metallic nanoparticles; application of large-scale DFT calculations to model nanoparticle sequences to show size and oxygen adsorption coverage trends, and finally the application of these techniques and knowledge to perform a study of oxygen adsorption on real-world, experimentally determined platinum nanoparticles in collaboration with the Nellist group at Oxford materials. We explore the binding of atomic oxygen to cuboctahedral platinum nanoparticles of up to 1000 atoms using DFT calculations in ONETEP. We demonstrate convergence to the infinite slab limit for single oxygen adsorption in chapter 4 and correlate adsorption strength against popular descriptors for catalytic activity, such as the d-band centre approach. This approach is possible because of work which will be described in chapter 3 to implement angular momentum projected density of states calculations in ONETEP. The effects of oxygen coverage on the Pt55 and Pt147 cuboctahedral nanoparticles will also be analysed, which serves to advance our simulations towards realistic conditions. We show in our investigation into half monolayer, hemispherical oxygen coverage on platinum nanoparticles that oxygen tends to gravitate towards the edges and lower coordinated sites in the nanoparticle and away from the centres of facets. This effect correlates with the site specific, single oxygen adsorption energies on Pt309 and experimental platinum nanoparticles which is presented in chapter 5. We show that when subdividing the binding of monolayers of oxygen into only (111) and (100) facets that these have a lower adsorption strength per oxygen atom than combined (100) and (111) facets as well as lower binding strength than single oxygen adsoprtion. In the next part of the study, which is discussed in chapter 5, we show large scale DFT calculations on real platinum nanoparticles, which were measured by the Nellist group at Oxford materials using advanced electron microscopy techniques. These DFT calculations provide the electronic structure of the experimentally measured nanoparticles, which allowed us to apply electron density based catalytic activity descriptors to the nanoparticles, such as the d-band centre approach, or our own electronic density based descriptor described in chapter 3. We find that surface roughness of the experimental nanoparticles contributes to more potential oxygen binding sites with low electron density, which correlatates with stronger oxygen adsorption strength in our model, when compared with the relative smoothness of cuboctahedral and truncated octahedral facets. In the analysis which is presented in chapter 5, the proportion of sites which lie within 0.2 eV of the oxygen binding strength required for optimum catalytic activity is predicted with high efficiency, based on our catalytic activity descriptor. Finally, in chapter 6 we describe a new method for large scale DFT calculations on metallic systems which we call the AQuA-FOE method. We show how this method can have a computational cost which increases effectively linearly with the number of atoms. The AQuA-FOE method works by implicitly heating and quenching the electrons in the system to find the oneparticle density matrix, while conserving the electron number. We show validation of this method inside the EDFT procedure by comparing numerically with the diagonalisation based EDFT that is already implemented in ONETEP showing agreement in the energies to better than 10⁻⁵ EH per atom. We will also demonstrate the effectively linear-scaling computational cost of our method with calculation times on regular truncated octahedral Palladium nanoparticles ranging from 2,406 to 12,934 atoms.

Resumen
Esta tesis presenta el desarrollo de nuevos métodos de nanofabricacion para la preparación de nanopartículas funcionales y electrodos interdigitados. El trabajo incluye el diseño, fabricación y caracterización de diferentes métodos que solucionan algunas de los retos que presenta la nanotechnología hoy en día. Estas estrategias aprovechan las ventajosas propiedades que surgen de las dimensiones nanometricas. En primer lugar, se ha desarrollado un método que facilita el estudio de la conductividad de una única nanopartícula. Este método está basado en la preparación de una plataforma donde se deposita una capa muy fina de un nuevo nanocompuesto. El nanocompuesto está formado de nanocristales embebidos en una resina altamente aislante. Esto facilita la conexión de las nanopartículas usando una punta de AFM mientras estas están aisladas eléctricamente del medio. Se exponen el diseño y optimización de la técnica, además de los resultados preliminares obtenidos de las medidas eléctricas. Además, se han fabricado nanopartículas metálicas mediante litografía por nanoimprint. Esta técnica es un avance en el estado del arte, ya que permite la fabricación de nanoestructuras con una alta relación de aspecto, facilita el liftoff, y proporciona una alternativa para obtener nanopartículas de diferentes tamaños, formas y materiales, incluso combinaciones de estos. También se ha evaluado el comportamiento de las partículas como plasmones de resonancia para su aplicación en sensores LSPR (localized surface plasmon resonance). Se ha presentado el desarrollo de la fabricación y caracterización de nanoelectrodos interdigitados para usar como (bio)sensores, incluyendo la adaptación de métodos de nanolitografía y encapsulados. La caracterización funcional de los nanoelectrodos interdigitados demuestra una mejoría en la selectiva detección de dopamina en presencia de ácido ascórbico debido a la miniaturización de los dispositivos. Los resultados experimentales han sido confirmados mediante simulaciones de elementos finitos. En esta tesis, se ha demostrado que los nuevos métodos desarrollados permiten la fabricación de nanoestructuras y nanodispositivos con nuevas y mejoradas funciones. Además, los métodos presentados pueden ser aplicados a otras áreas como los biosensores, la nano/microelectrónica, medicina o energía.
This thesis presents the development of novel nanofabrication methods for the preparation of functional nanoparticles and interdigitated nanoelectrodes. The work includes the design, fabrication and characterization of different approaches that overcome some of the current challenges in nanotechnology. These approaches take advantage of the enhanced properties that arise from the nanometer scale dimensions. First, a novel method to study the electrical conductivity of single nanoparticles has been developed. This method is based on the preparation of a platform where a thin film of a new nanocomposite is placed. The nanocomposite is composed of nanocrystals embedded in a highly isolating resist. It facilitated the connection of the particles by AFM tip while keeping them electrically isolated from their surroundings. The design and optimization of the method, as well as the preliminary electrical results have been exposed. Moreover, metallic nanoparticles arrays have been fabricated by nanoimprint lithography. This technique is a step forward in the nanoimprint lithography’s state of the art, since allows the fabrication of high aspect ratio nanostructures, facilitates the lift-off, provide alternative to obtain nanoparticles of different size, shapes and materials, and even combination of them. Plasmonic resonance behavior of the particles has also been evaluated for their application as localized surface plasmon resonance (LSPR) sensors. In addition, fabrication and characterization of interdigitated nanoelectrodes to be used as (bio)sensors have been developed, including the adaptation of nanolithography methods and packaging strategies. The functional characterization of the interdigitated nanoelectrodes showed an improvement on the selective detection of dopamine in presence of ascorbic acid resulted from the miniaturization of the devices. The experimental results are correlated to finite element simulations. In this thesis, it is demonstrated that the new developed methods allow fabricating nanostructures and nanodevices with novel and enhanced functionalities. Moreover, the presented methods can be further applied to different areas, such as biosensors, nano/microelectronics, medicine or energy.
