摘要：

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. (C) 2008 Elsevier B.V. All rights reserved.
