Texte intégralDuring this work, we were interested in the design of plasmonic particles for the control of the absorption and the emission of light. Our strategy was to synthesize core@shell nanoparticles made of a gold core and a silica shell containing fluorescent organic molecules. We have varied the distance between the emitters and the core in order to tune their coupling with the plasmons of gold. We thus tuned the optical properties of the particles. We were also interested in the assembly of these nanoparticles to get supra-particles or organized two-dimensional networks. The study of optical properties of these new materials showed that the exaltation of the fluorescence is maximal when the core@shell particles are confined between two gold boundaries, this situation corresponding to a strong cavity mode. We also worked on the synthesis of particles consisting of a silica core and either a gold shell with bare patches or a titanium dioxide shell with patches covered with gold nanoparticles

Texte intégralIn the field of biosensors, efficient absorption of the electromagnetic field in a confined space is essential. The use of metallic nanoparticules comparable to metamaterials is the best way, to date, to amplify the field. In fact, by placing a dielectric film between a metal substrate and these particules, we allow the propagation of a gap-plasmon under these particules. This locates the magnetic field under these particules and the electric field on the edges of these nanoparticules. The resonances of this system are very sensitive to the environment of the gap-plasmon which allows very precise analysis. Although we can explain where these resonances come from, the efficiency to absorb of these structures remains poorly understood. The interferometric control is a response to this efficiency. In this report, I show that interferometric modeling of this system can fully explain the absorption. Indeed, the interferometric control well explains the presence of resonances at specific wavelenghts or the appearance of resonances when the angle of incidence is not normal. This study is very important to understand and master biosensors. In addition, this model can explain the amplification of the field in these structures and will allow us to provide the resonances of a system in various environments

Texte intégralThis study deals with the self-assembly of dimpled patchy particles to get new colloidal molecules. First, building blocks – patchy silica nanoparticles and satellite particles - were synthesized. This work was focused on particles bearing four patches whose morphological purity was increased not only by optimizing the surface functionalization of the seeds used during the seeded growth emulsion polymerization stage, but also by purification by density gradient centrifugation. Covalent chemistry allowed obtaining colloidal molecules consisting of a four-patch particle surrounded by controlled number of satellite nanoparticles. The chemical pathway was simplified by reducing the number of functionalization steps for the polystyrene chains anchored at the bottom of the dimples and for the surface of the satellite particles. Colloidal molecules whose morphology mimics that of water molecules were fabricated by adjusting the ratio between the number of satellite particles and the number of dimples. Due to the sizes of the particles involved, dynamics of assembly cannot be followed by optical microscopy. This is why the technique of transmission electron microscopy in liquid phase was also investigated

Texte intégralMetamaterials are a novel class of artificial composite materials, typically made of subunit called meta-atoms and exhibiting unusual properties. Such meta-atoms, have to be architecturedat the nanometric level, to induce as extraordinary properties as a negative refractive index. In thiscontext, we developed patchy particles, capable to create interactions along predetermined directions.Multipodic clusters made of those (dielectric) particles surrounded by a controlled number ofplasmonic satellites (gold) were developed. We focused on isotropic clusters deriving fromtetrahedral, octahedral and icosahedral geometry (three of the fifth Platonic solids). For that purpose,we used silica/polystyrene clusters, obtained from seeded emulsion polymerization, as template. Byderiving those clusters, patchy particles bearing dimples containing grafted residual polystyrene chainswere obtained. By chemically deriving those chains, we explored two synthetic pathways, thedecoration of the dimples with gold colloids subsequently grown or the anchoring of silica satellitesonto which gold shells were subsequently grown. The second one was prove to offer a better controlover the cluster morphology as well as the inter-satellites gap (few nanometer) which is pivotal toensure an optimal plasmonic coupling. Then, the optical properties of the as obtained clusters weresimulated and measured

Texte intégralThis study deals with the assembly of patchy particles to get new materials. The state-of-the-art allowedus to select and implement an original strategy whose driving force is the solvent-induced assembly, i.e. based onthe stickiness of polystyrene (PS) macromolecules when they are subjected to a mixture of good and bad solvents.We investigated the assembly into clusters, chains or monolayers of one-patch, two-patch or three-patch silicananoparticles (NPs), respectively, the patches being PS macromolecules grafted at specific positions on theirsurface. One-patch silica NPs with controllable patch-to-particle size ratio were successfully synthesised throughphase separation and site-specific silica coating. Their assembly was performed in DMF/ethanol binary mixtures.The effect of the solvent quality, centrifugation force, particle concentration, incubation time and patch-to-size ratiowas investigated and discussed. The strategy was spread to obtain gold-coated clusters. The two-patch silica NPswere prepared through a seed-growth emulsion polymerisation of styrene and the patch-to-particle size ratio wasadjusted through the extent of the silica core regrowth. The chaining of the NPs was efficiently achieved in theTHF/NaCl aqueous solution mixtures by varying the NaCl concentration, solvent quality, incubation time, NPsconcentration and patch-to-particle size ratio. We showed that the kinetics of the chaining process is characteristicof a reaction-controlled step-growth polymerisation. Strategies to mimic homopolymers, random copolymers, blockcopolymers and branched polymers were implemented by using one-patch NPs, two-patch NPs with different sizes/surface chemical functions and/or three-patch NPs as building units. The three-patch silica NPs were obtainedthrough the same synthetic pathway than two-patch ones. For assembling them in honeycomb-like 2-D structures,we used the Langmuir technique.and we studied the influence of different experimental parameters. THF vapourannealing was implemented to reinforce mechanically the assembly but without significative effect on the packingdensity
Yammine, Elham. « Synthèse de nanoparticules de latex de polystyrène à patchs magnétiques ». Thesis, Bordeaux, 2019. http://www.theses.fr/2019BORD0397.
Texte intégralMagnetic patchy particles are of great interest for assembly into novel colloidal structures. The state of the art showed us that the vast majority of synthesized and studied systems concerns particles with a single magnetic patch, thus limiting the structures accessible by particles assembly. Therefore, the main goal of the present study was to develop spherical polystyrene (PS) nanoparticles with two or many superparamagnetic nanoparticles on their surface. Our multistep process involved first the fabrication of Magnetic Janus particles (MJPs) by seeded-growth emulsion polymerization and subsequent incubation in suitable mixtures of good and bad solvents to make their polystyrene lobe “sticky”. MJPs are then ready to coalesce into self-assembled structures with small aggregation numbers. In order to obtain magnetic patches with a size range of 100 nm, we prepared colloidal supraparticles highly loaded with superparamagnetic iron oxide nanoparticles through a multistep procedure, including evaporation-induced emulsion, silica coating and purification, leading to a narrowing of the size distribution. The optimal parameters of the seeded-growth emulsion polymerization (surfactant mixture composition, coupling agent type, surface grafting density) and of the assembly (solvent quality, good solvent content, particle concentration, temperature and incubation time) were previously determined with silica nanoparticles as models with similar particle diameter as well as surface chemistry. We demonstrated that under the same conditions MJPs synthesis became trickier, mainly because of the small amount of available supraparticules. This led us to implement new seeded-growth emulsion polymerization conditions. Finally, batches of latex nanoparticles with two or three magnetic patches were obtained, but required further purification steps before investigating their assembly behavior under magnetic field
