Nanomechanical Sensor Platform Based On Piezo-Resistive Cantilevers

This paper presents Cantion’s cantilever-based bio/chemical sensor. The cantilevers have integrated readout and can be used both in liquids and gases. The sensing principle is based on a cantilever bending due to a change in surface stress. Such surface-stress change is obtained during molecular interaction which has made it possible to measure DNA hybridization, antigen-antibody interactions etc. This paper presents Cantion’s technology and instruments and furthermore discusses different types of applications realized on the platform. Finally, the perspective of using Cantion’s cantilever sensor technology for the next generation handheld application is discussed.
