30 April 2008 Micromechanical sensors based on conformational change of proteins
Author Affiliations +
Microcantilevers (MCLs) hold a position as a cost-effective and highly sensitive sensor platform for medical diagnostics, environmental, and fast throughput analysis. One of recently focus in this technology is the development of biosensors based on the conformational change of proteins on MCL surfaces. The surface stress changes due to conformational change of the proteins upon interaction with specific analytes are promising as transducers of chemical information. We will discuss our recent results on several biosensors due to conformational change of proteins. The proteins include glucose oxidase (GOx), organophosphorus hydrolyses (OPH), Calmodulin (CaM), and Horseradish peroxidase (HRP).
