Abstract: This account summarizes recent research in my laboratory on the integration of organic functionalities to silicon surfaces. We have discovered and developed novel, two-step strategies for the assembly of organic monolayers on silicon, silica, and related materials. These methods are simple and reproducible and lead to close packed monolayers with excellent physical/chemical properties. Exciting applications of these monolayers include (a) resists in soft-lithography, particularly micro-contact printing; (b) monolayer lubricant in silicon based micromachines, also called micro electromechanic systems (MEMS); and (c) molecular basis for the immobilization of DNA and protein molecules in microarrays.

Key words: Silicon surface, Self-assembled monolayer, Micro contact printing, MEMS (Microelectromechanical systems), DNA chip, Protein chip
