The most reported SiNW-based detectors are essentially in field effect transistor (FET) configuration. Namely, single or few SiNWs, prepared as single-crystal and successively functionalized, are connected to source and drain electrodes by forming the active channel whose conductivity changes in response to molecular recognition.[9–16] Successful fabrication of ultrasensitive SiNW–FET sensors has been demonstrated for ions, small molecules, proteins,[10, 14] DNA, viruses, and neuronal cells. However, ...
