    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.

    摘要： There is provided a biomolecule FET enhancing a sensitivity. The biomolecule FET includes a substrate, first and second impurity regions formed on both sides of the substrate, and doped with impurities of a polarity opposite to that of the substrate, a gate formed on the substrate and being in contact with the first and second impurity regions, and a probe biomolecule attached to the gate. A region of the gate adjacent to the first impurity region is wider than a region thereof adjacent to the second impurity region. A density of the probe biomolecule attached to the surface of the gate is increased, and when detecting a level of hybridization of the probe biomolecule and the target biomolecule, its sensitivity is improved.
