The integration of microelectronics technology with molecular biology is having a transforming impact in the development of biosensors with potential applications in future drug and diagnostic development.  By the use of miniaturization techniques, the sensing elements or at least parts of them are now getting shrunk down to the same order of dimension as the bio molecules being sensed, resulting in the improvement of many attributes of the molecular detection processes. My research focuses on the development of such microsensors for diagnostic purposes.
