High sensitivity piezoresistive cantilever sensor for biomolecular detection [PDF]

open access: yesJournal 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.

In-plane nanoelectromechanical resonators based on silicon nanowire piezoresistive detection [PDF]

open access: yesNanotechnology, 2010
We report an actuation/detection scheme with a top-down nano-electromechanical system for frequency shift-based sensing applications with outstanding performance. It relies on electrostatic actuation and piezoresistive nanowire gauges for in-plane motion transduction. The process fabrication is fully CMOS compatible.
