Functionalization and 2-photon Patterning of Photopolymers for 1D and 3D Directed Assembly of Nano-objects ; Assemblage dirigé de Nano-objets en 1D et 3D par fonctionnalisation et structuration à 2 photons de photopolymère
Abstract
The precise patterning of nanoparticles (NPs) with fine control of their spatial positioning and orientation is highly desirable. Their selective assembly in multiple dimensions and on continuous length scales would lead for the formation of collective properties that differ from those of individual particles providing astronomical potential to many applications. In this context, the 3D patterning of metallic NPs offer the potential to increase the number of electromagnetic “hot spots” towards new generation of integrated and ultrasensitive sensors. In this thesis, we present a general strategy for the immobilization of NPs, particularly gold, on 1D and 3D polymer micro templates. This strategy involves the functionalization of photopolymers and their 2-photon polymerization to fabricate microstructures that selectively attract colloidal NPs with suitable ligands allowing their precise organization even within complex 3D structures. We show monolayers of NPs without aggregations collecting a clean surface besides that the surface density of NPs on the polymer surface can be controlled. We deeply investigated the functionalization mechanism of photopolymer and the interaction of the polymer surface with NPs. Finally, we show the potential of our functionalization strategy for multiple applications including SERS detection of chemicals ; L’organisation de Nanoparticules (NPs) sur des motifs complexes structurés en 3D est un challenge d’actualité. Une telle nanostructuration devrait donner lieu à des propriétés collectives permettant l’émergence de très nombreuses applications originales. Dans ce contexte, le contrôle de l’organisation des NPs plasmoniques en 3D est une approche prometteuse pour augmenter le nombre de « points chauds » électromagnétiques et proposer ainsi une nouvelle génération de capteurs intégrés et ultrasensibles. Dans cette thèse, nous proposons un procédé universel pour assembler des NPs et plus particulièrement d'or sur des motifs polymères structurés en 1D et 3D. La méthode implique la ...
