摘 要：Cantilever-based sensors present a platform for monitoring chemical reactions and detecting chemical compounds based on nanomechanical effects. Cantilever sensors have become popular because they offer rapid, label-free sensing possibility in a miniaturized platform, readily opening up applications for hand-held and portable devices [1-3]. The sensing ability of the cantilevers is intrinsic since the range of molecules/chemicals that can be detected is not determined by the sensor itself but on the available receptor coatings. The cantilever sensor is simply a transducer of the chemical reactions occurring on its surface.
