Abstract

A nanomechanical microcantilever promises to bring about revolution in the field of chemical and biological analysis system development. We report the peptide immobilized nanomechanical microcantilever operated in dynamic vibration mode for quantitative label-free detection of protein kinase A. The detection principle of dynamic cantilever is that specific interaction on the microcantilever surface lead to the dynamic response change of microcantilevers. We achieved the protein kinase A detection in the low concentration as much as 6.6 pM through measuring the dynamic response change of microcantilever.
