Abstract: Microcantilever sensors have attracted tremendous attention and numerous biological and chemical detections have been demonstrated. In comparison to conventional sensing techniques, the major advantages of microcantilevers include high sensitivity and quick response, direct detection (label free), low cost, versatility, array capability (small size and microfabricationable). The review covers the basic working principles and sensing mechanisms, the major types of microcantilevers, and the reported applications in biological and chemical detections.

Keywords: Microcantilever sensors, Biological and chemical detection, Detection sensitivity
