High sensitivity piezoresistive cantilever sensor for biomolecular detection [PDF]

Journal of Physics: Conference Series, 2006
Micro-cantilevers are now gaining popularity in biomolecular sensing. Monitoring and mass detection of biological species can be accurately determined using the micro- or nano- scale cantilevers. The targeted biological molecules are first immobilized onto the microcantilever which is later determined through static or dynamic techniques.
