    Abstract: The present invention relates to a biomolecule-based electronic device in which the biomolecule with redox potential is directly immobilized on the substrate. The present invention enables to excellently exhibit the capability of a protein-based bio-memory device in which it is preferable to use the substrate on which cysteine-introduced recombinant proteins are effectively immobilized and a self-assembled layer (SAM) is fabricated. It becomes realized that a redox potential is regulated using intrinsic redox potential of the protein dependent on applied voltage. The present invention provides a novel operating method in which three potentials are applied throughout four steps. The present invention has some advantages of fabricating a protein layer in a convenient manner and inducing electron transfer by fundamental electrochemical or electronic operation. The method of this invention is considered as a new concept in the senses that intrinsic electron transfer mechanisms induced by natural-occurring biomolecules are used to develop an information storage device.

    Abstract: 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.

    Abstract: Provided is a method of separating particles, the method comprising: forming a first chamber and a second chamber separated by an interface with a pore, wherein the first and second chambers have electrodes with different polarities; placing particles to which a target biomolecule is bound from particles to which the target biomolecule is not bound in the first chamber; applying a voltage which has the same polarity as that of the target biomolecule to the electrode of the first chamber, and a voltage which has an opposite charge to that of the target biomolecule to the electrode of the second chamber; and translocating only the particles to which the target biomolecule is bound from the first chamber to the second chamber through the pore. Conventionally, the size of a pore is used to separate biomolecules. However, effective separation is difficult to achieve because the manufacture of a pore with a diameter of less than 10 nm, small enough to separate biomolecule, is not easy. Therefore, signal separation and data analysis must be required. However, in the present method, physical movement induced by the charge of biomolecules is used to effectively separate the biomolecules, thus obtaining a high signal to noise ratio. As a result, additional data analysis is not required.
