摘要： Provided are a sensing switch and a sensing method using the same. The sensing switch includes: a substrate; a supporter on the substrate; a sensing plate that is connected to a side of the supporter and is in parallel with the substrate by a predetermined distance; a receptor binding region on an upper surface of an end portion of the sensing plate; an electric or magnetic field generation device that induces deflection of the sensing plate when a receptor bound to the receptor binding region is selectively bound to an electrically or magnetically active ligand; and a pair of switching electrodes that are separated by a predetermined distance and is connected when the sensing plate contacts the substrate due to the deflection of the sensing plate. A target material need not be labelled, a signal processing of a fluorescent or electrical detection signal using an analysis apparatus is not required, and a signal can be directly decoded by confirming whether a current flows through the switch.

The FET-based biosensor can be manufactured using a semiconductor fabrication process without performing an additional process. Therefore, the inorganic film can be selectively deposited on a surface of a specific gate of a single FET, or on the surfaces of some gates of a plurality of FETs using patterning. Furthermore, the FET-based biosensor can be used to effectively detect trace amounts of a target biomolecule in a sample.
