Abstract:

Catalytic nanoreactors, prepared by the Layer-by-Layer encapsulation of zeolite H-Beta, were used in the dynamic kinetic resolution (DKR) of 1-phenylethanol and 1-indanol. Yields for both alcohols were clearly above 50%, with ee’s over 85%, indicating successful protection of the pH-sensitive enzyme, candida antarctica lipase B, from the acidic zeolite. Attention proceeded to the DKR of amines, which can involve the undesired hydrogenolysis reaction during the racemisation step. Thus, the phenomenon of hydrogenolysis was investigated.

2010 - 2011<br>The increase in dietary-intake-related illnesses, such as obesity, cardiovascular diseases, hypertension, diabetes and cancer, have made in recent years the development of health-and-wellness promoting foods a priority of the food industry. Clinical studies have demonstrated tangible health benefits that may be derived from the intake of bioactive compounds. However many difficulties are associated with their inclusion in food matrices, due to a very low solubility in water and easy degradation by hostile environmental conditions once extracted from plant tissues.

Abstract:

Bacteria biohazards, such as Anthrax, are responsible for causing mild to serious illnesses in humans and animals. The primary aim of this research study was to develop a rapid one step assay to detect and neutralize bacteria-based biohazards, using an Immunoliposome-nanoparticle complex. An Anthrax model, Bacillus cereus, was grown for 3 hours and diluted 1:25 in media (2.0 x 107 cfu/ml). The Bacillus cereus was interacted with an Immunoliposome-nanoparticle complex containing an MgO-C 2 neutralization agent. The samples were analyzed via flow cytometry with a 1:8:1 ratio Bacillus cereus, Imm

Abstract:

Glycation of whey proteins results in food-grade composites with modified physicochemical properties. Here, the reaction between glucose and bovine serum albumin (BSA) is promoted under wet-heating conditions. The glycated protein is characterized in depth and compared to the native counterpart and the impact of glycation on properties like net surface charge, particle size and surface hydrophobicity are observed. Conjugation with glucose reduced the surface hydrophobicity of BSA but the interactions between albumin and curcumin became stronger, which contradicts the direct relationship betwee

Pollution, poor nutrition, insufficient physical activity, and the use of tobacco and alcohol are the primary cause of most chronic and aging-related diseases.

This process negatively affects the equilibrium of local gut microbiota and leads to systemic oxidative damage of cellular biomolecules (lipids, proteins and nucleic acids), thus, playing a major role in the development of chronic and degenerative illness such as cancer, autoi

Abstract:

In this thesis we developed three copper-containing systems. Copper shows intriguing abilities in photocatalysis, however, one of the major limitations of many copper complexes is that photochemical properties might be quenched in solution caused by π-interactions between solvent and solute, due to Jahn-Teller distortion in the excited state. As such, we herein seek to synthesise copper heteroleptic complexes that will subsequently be nanoprecipitated with a polymer. This will allow the polymer to encase the complex and prevent the solvent-induced quenching. Subsequently, the preparation of

GBM is considered to be an incurable malignancy as these tumours evade all intricate attempts of therapy and no contemporary chemotherapeutic regimen is effective.

Abstract:

This thesis focuses on the interactions between milk proteins (caseins) and tea catechins and the consequences of the interactions on the renneting properties and digestion of casein micelles as well as on the biological functionality of the mixture, as measured using intestinal cell models. The binding of epigallocatechin-gallate (EGCG) to casein micelles was quantified using HPLC and fluorescence quenching, and it was shown that a substantial amount of EGCG can be incorporated in the casein micelles. At concentrations < 2.5 mg/ml milk, most of the EGCG added to milk was associated with the

Abstract:

Research Doctorate - Doctor of Philosophy (PhD)<br>The application of nanotechnology in pesticide delivery is relatively new but has created many opportunities in reducing the losses of pesticides to the environment and ensuring their safe application. Of the various potential applications of nanotechnology, the nanoencapsulation process for pesticide delivery is one of the promising fields of current research. The focus of ongoing research is on the development of nanoencapsulated pesticide formulations that have slow releasing properties with enhanced solubility, permeability, and stability.

Abstract:

Currently, therapeutic proteins and peptides are delivered subcutaneously, as they are readily denatured in the acidic, protease rich environment of the stomach or gastrointestinal track and low bioavailability results from poor intestinal absorption through the paracellular route. Encapsulation of therapeutic peptides and proteins into polymeric micro- and nano- particle systems has been proposed as a possible strategy to overcome limitations to oral protein administration. Furthermore, it was shown that nanoparticles having diameters less than 5µm are able to be taken up by the M cells of P

Abstract:

L’utilisation non raisonnée d’insecticides a des conséquences sur l’environnement et la santé humaine mais aussi sur le développement de résistances chez les insectes nuisibles. Dans ce contexte, ce travail de thèse porte sur le développement d'une technique de nanoencapsulation d'un agent synergisant chimique, la deltaméthrine (pyréthrinoide), associé un pro-insecticide l’indoxacarbe (oxadiazine). Sur la base d’études in vitro sur cellules neurosecrétrices de blattes (Periplaneta americana), une action synergique entre la deltaméthrine et le DCJW (métabolite actif de l’indoxacarbe) a été démo

Abstract:

Depuis leur découverte, les nanotubes de carbone (CNT) ont connu de nombreux succès en raison de leurs performances mécaniques, électriques et thermiques exceptionnelles. L'exploitation de ces propriétés requiert néanmoins de pouvoir isoler les CNT, de les manipuler et de les localiser au sein d'un matériau d'architecture plus ou moins complexe. Pour cela, il est souvent nécessaire de disperser les CNT en raison de leur très grande insolubilité dans tout solvant. De nombreuses stratégies de dispersion reposent sur la stabilisation des CNT par des tensioactifs. Cependant, très peu d'études vise

Abstract:

In the last few decades considerable attention by the pharmaceutical field has been paid to the incorporation of nanotechnology in the production of new drug delivery systems (DDS). In the turn of the millennium several research groups centered their attention in the proficient features of lipid nanoparticles (L-NPs). The reduced particle size, large surface area, biocompatible and biodegradable nature, high payload, possibility of controlled release of the active pharmaceutical ingredient (API) and the facility of large scale production are some of the appealing advantages of L-NPs. Moreover,

Nowadays, there is a trend towards a healthier way of living as well as a growing awareness by consumers what benefits for the health certain ingredients have in maintaining it. Preventing diseases through diet is a unique opportunity to use new functional foods. The development and achievement of functional foods requires technologies for incorporating of these investigated health promoting ingredients into food without reducing their bioavailability or functionality. A very interesting example of new functional foods is microalgae. Our laboratory is investigating the special properties of S

This has spurred research into nanocapsules which has proved to overcome most of the drawbacks that plagued microcapsules by being able to evade the reticulo-endothelial system, exhibit enhanced permeability and retention in tumours etc. The capsules fa
