Paper Abstract

We present a novel technique for immobilizing nanoparticles on a substrate. This method contains two techniques, which are a preparing technique of self-assembled monomolecular layers (SAMs) terminated in an epoxy group or an amino group on surface of nanoparticles or a substrate and a reaction technique between the epoxy and amino groups. The epoxy terminated SAMs or the amino terminated SAMs were prepared on nanoparticle surfaces or a substrate surface by a chemical adsorption technique using 3-glycidoxypropyltrimethoxysilane or (3-aminopropyl) trimethoxysilane. The particles dispersed in an organic solvent were coated on the substrate, and then the epoxy and amino groups were reacted each other. Unreacted nanoparticles were removed by washing. As a result, the nanoparticles were immobilized to the substrate surface through covalent bonds of the epoxy-amine cross-linking. By using this method, a mono nanoparticle layer could be formed on the substrate.
