“…Biosensors, which convert biology excitation into measurable signals, are gaining interests across different research areas including biology, chemistry, electrical & electronic engineering, and mechanical engineering. A typical biosensor usually consists of three parts: a biological recognition element, a transducer, and a detector element [1]. As one of the most common type of biosensors, microcantilever biosensor has been used to detect prostate cancer by identifying prostate-specific antigen [2], humidity [3], herbicide [4], metal ion [5], temperature and radiation [6] by applying specific biological recognition element on the cantilever surface.…”
