Abstract

Microcantilever based biosensors were born in 1941 and they are an adaptation of the atomic force microscope (AFM) in which preferential adsorption of target molecules to receptors coating one side of the cantilever leads to a measurable bending response. Microcantilevers, with force constants in the range of 0.008 N/m to 0.5 N/m have been shown to be highly sensitive transducers for a variety of environmental factors including chemical binding, temperature and humidity.Due to their sensitivity and small size, microcantilevers have proved to be useful in biosensing and many other applications. In this paper, I tried to optimize microcantilever design, in order to have good sensing and high performance.
