The reported techniques can also be applied to other fields relying onįunctionalized GFETs, such as gas or chemical sensing or infrared imaging. This platform offers a truly statisticalĪpproach on GFET based biosensing and further to quantitative and multi-analyte We used sidewall spacer etching to fabricate polycrystalline silicon NWFET sensors. This study explored the effect of nanowire dimensions on sensors’ sensitivity. Of the sensing platform array with 512 GFETs in simultaneous detection for Silicon nanowire field effect transistor (NWFET) sensors have been demonstrated to have high sensitivity, are label free, and offer specific detection. An n channel is induced at the top of the substrate beneath the gate. ![]() As an important step towards that, we report wafer-scaleįabrication of CMOS integrated GFET arrays with high yield and uniformity,ĭesigned especially for biosensing applications. The enhancement-type NMOS transistor with a positive voltage applied to the gate. Nanomaterials, are among the most promising technologies for label-freeĮlectrical biosensing.
