Current readout has been a known technique since the inception of electronic sensors and is widely used, for example, in radiation detectors, impedance spectroscopy, and mechanical sensors. Recently, new challenges have emerged for current sensing in the upcoming era of nanosensors. Nanowires, carbon nanotubes and nanopores are emerging devices that have been proven to be effective in sensing ultra-low concentrations of target molecules [1]. For those devices, current sensing becomes… CONTINUE READING
