Ultrasensitive bio-detection using single-electron effect

Abstract: Nanosized particles can detect minute changes in surrounding electric fields via a phenomenon known as single-electron effect. Sensitivity can reach as much as counting single electrons. This phenomenon promises the possibilty of detection of atoms, molecules, cells or pathogens passing over or suspended around the nanosized particles whose IV characteristics is being monitored. Unfortunately, practical realization of such devices has been challenging because of their small size and low operating temperature, … Show more
