摘要

The paper reports a novel static cantilever sensor (surface-stress-style) with long-term repeatable detecting sensitivity to trace TNT vapor. A siloxane-based TNT-sensitive bi-layer is self-assembled directly on the SiO2surface of the surface-stress-style micro-cantilever. This method is, for the first time, used to replace the traditional self-assembled monolayers (SAMs) of thiols on Au (111) surface to solve the problem of the long-term instable Au-S bond.
