Chemical engineering of silicon oxide surfaces using micro-contact printing for localizing adsorption events of nanoparticles, dendrimers and bacteria
Résumé
A simple surface chemical bi-functionalization procedure, involving micro-contact printing of silane molecules is presented. The printing process has been optimized for obtaining high quality layers of good homogeneity. The produced chemical templates are used in order to spatially localize the adsorption of different entities diluted in liquid solution. By combining optical and Atomic Force microscopy we confirm the selective adsorption of gold nanoparticles, dendrimers and bacteria.
