Highly sensitive, low-cost integrated biosensors

Recently there has been an increasing interest in the development of electronic sensors for the detection and identification of biological species. For example, label-free DNA detection has been made possible by the use of field-effect sensors. In these sensor systems, the intrinsic charge of DNA molecules is detected through the use of metal-oxide-semiconductor field-effect transistors (MOSFETs) in which the gate electrode has been removed and …
