Field effect transistor (fet) based sensors have been widely investigated due to their advantages of miniaturization, easy integration, label-free detection and direct transduction , , ion sensitive field effect transistors (isfet) were first proposed by bergveld in 1970  , and have since found common applications as ph sensors. The last years in particular, silicon nanochannel field effect transistor (fet) biosensors are one of the most promising technologies in the development of highly sensitive device for cancer diagnostics semiconducting nanowires (nws) are used for making better transistors such as silicon. High sensitivity ph sensing on the beol of industrial fdsoi transistors field effect transistor (fet) diagram of a mos transistor: nwell in light blue, silicon dioxide layers in yellow, gate stack in light orange, depleted channel in light blue, source and drain implants in purple, aluminum vias in black.
