We herein report the design of a novel semiconducting silicon nanowire field-effect transistor (SiNW-FET) biosensor array for ultrasensitive label-free and real-time detection nucleic acids. Highly responsive SiNWs with narrow sizes high surface-to-volume-ratios were "top-down" fabricated complementary metal oxide semiconductor compatible anisotropic self-stop etching technique. When covalently modified DNA probes, nanosensor showed highly sensitive concentration-dependent conductance change...
Silicon nanowire (SiNW) field effect transistors (FETs) have emerged as powerful sensors for ultrasensitive, direct electrical readout, and label-free biological/chemical detection. The sensing mechanism of SiNW-FET can be understood in terms the change charge density at SiNW surface after hybridization. So far, there been limited systematic studies on fundamental factors related to device sensitivity further make clear overall sensitivity. Here, we present an analytical result our triangle...
