Nanoparticules en environnement cellulaire : Impact de la nano-architecture sur l'internalisation, la biodégradation et les fonctionnalités thérapeutiques. by Anouchka Plan( )

1 edition published in 2019 in French and held by 1 WorldCat member library worldwide

Inorganic nanoparticles represent innovative solution to face current limitations in early diagnostic or targeted therapies.First part focuses on the interactions between magnetic nanoparticles and stem cells to understand better the parameters which impact internalization and biodegradation. We evidenced an impact from the nanoparticle's coating, the presence of proteins and the aggregation. Nanoparticles' impact on cellular differentiation shown a process of re-magnetization of the iron products of degradation for some differentiation ways.In the second part, we studied anti-cancerous hyperthermal therapies and more precisely the impact of the intracellular confinement. We shown that the cellular environment can completely inhibit the heating delivered by magnetic hyperthermia but at the contrary can also be beneficial for applying photothermia at biocompatible wavelengths. Finally, the combination of photothermia with a drug leaded to an increase of the efficiency of both therapies separated with reduces secondary effects
Electromouillage et fiabilité : investigation de matériaux diélectriques et de couches minces hydrophobes by Gwenaël Bonfante( )

1 edition published in 2017 in French and held by 1 WorldCat member library worldwide

In order to increase the technologies reliability using electrowetting, this work aims to study the mechanisms of ageing on dielectric and hydrophobic materials used in electrowetting as well and to apply this study to new materials. This thesis is composed of three parts.First, to be able to characterize precisely the hydrophobic properties of these surfaces and especially their surface polarity, we established a method to measure the surface polarity based on wettability of two liquids on a surface permitting a better precision with less measurements. In a second part, we studied different films used in electrowetting before and after ageing around 90°C for one week in order to simulate a long term ageing at an ambient temperature. Widely used hydrophobic coating used in optical systems and lab-on-chip will be mainly characterized such as Fluoropel©, Cytop© and parylène C. This work shows the visible alteration of material performances in a reproducible way. Wetting hysteresis and natural contact angle with the cohesive properties of the coatings are studied in order to establish critical parameters for the life time.Finally, we tried to establish a method to deposit a hydrophobic metal oxide coating by two ways, sol-gel technic with dip-coating deposition and by PVD. A precursor sol made of the metal usable to deposit its oxide thin films has been elaborated. The solution is prepared from the synthesized precursor and stabilized by chelatant (acetylacetone). The solution stability as well as the deposition method used are presented and the annealed coatings deposited by sol-gel and PVD are characterized by XRD and morphologically (SEM, optic microscope ...). By the sol-gel method, covering coatings of about 300nm have been made. However, because of the roughness, no electrowetting experiments could have been achieved. By PVD, we have deposited coatings of 400nm thickness, very smooth and usable in electrowetting. These coatings give very good results in electrowetting on plane substrates and liquid lenses
Synthèse et propriétés photoélectrochimiques de nanoparticules d'argent intégrées dans des films d'oxydes mésoporeux by Nelly Couzon( )

1 edition published in 2018 in French and held by 1 WorldCat member library worldwide

L'étude et la compréhension des interactions existantes entre semi-conducteur et nanoparticules métalliques sous irradiation est primordiale pour l'amélioration de leurs performances. Dans cette étude, trois composites oxydes semi-conducteur-métal ont été synthétisés : TiO2-Ag, Fe2O3-Ag et WO3-Ag. La synthèse des films mésoporeux de TiO2, Fe2O3 et WO3 a été effectuée par voie sol gel à l'aide de copolymères à bloc, avec la méthode d'auto-assemblage induit par évaporation (EISA). Les nanoparticules d'argent sont formées dans un deuxième temps par réduction chimique de sels dans la porosité des films. L'étude photo-électrochimique de ces composites a permis de mettre en évidence différents phénomènes : le potentiel d'électroréduction des ions Ag+ dans une matrice de TiO2 mésoporeuse peut être modulé par l'effet de la lumière. Ce phénomène semble résulter d'un effet de passivation des NP Ag par TiO2 qui dépend des conditions d'insolation. Des effets de rechargement de l'électrode poreuse en espèce Ag+ ont aussi été observés, sous l'action simultanée de la chrono-ampérométrie et de l'irradiation
Fabrication et étude de nanomatériaux 1D conducteurs par électrofilage pour leurs propriétés optoélectroniques by Bastien Bessaire( )

1 edition published in 2016 in French and held by 1 WorldCat member library worldwide

The use of transparent and conductive materials has been growing exponentially in the last decade as they are part of many optoelectronic devices such as touch screens and solar cells. Among these materials, Indium-Tin Oxide (ITO) is the market reference since it combines a low resistivity and a high transparency up to 90% in the form of thin film. However, the growing in the development of flexible technologies created a real need in alternatives as ITO has poor mechanical properties. Carbon nanotubes and graphene are potential substitutes, but metallic nanowires and conductive polymers have been developed for their high performances and low cost respectively.This thesis presents the implementation of these alternatives by the original method of electrospinning and the study of their optoelectronic properties. The optimization of the experimental setup (field, rate, environmental parameters) and solutions (rheology, polymer concentration, co-solvents) allowed us to obtain 2 different kinds of nanostructures: fully polymeric with PEDOT:PSS and composite with PVP and silver nanowires. The study of the optoelectronic properties of the resulting networks has also been investigated
