摘要:
Provided is a method of preparing a patterned spot microarray using a photocatalyst. The method comprises coating the photocatalyst on a substrate to form a photocatalyst layer, coating a composition comprising a functional group to be connected to a biomolecule on the photocatalyst layer to form an organic layer, spotting the biomolecule on the organic layer, positioning a photomask above a spot of the biomolecule; and irradiating the spot through the photomask to pattern the spot.

A method of isolating nucleic acid from a sample containing nucleic acid is provided. The method includes contacting the sample with a bifunctional material that contains an amino group and a carboxyl group and is positively charged at a first pH to allow binding of the nucleic acid to the bifunctional material; and extracting the nucleic acid at a second pH higher than the first pH from the complex.

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.
