Bio-sensor having interdigitated micro-electrode using dielectric substance electrophoresis, and method for detecting bio-material using the same

Abstract

A biosensor of the present invention comprises: a first microelectrode and a second microelectrode arranged to intersect in a comb shape on a substrate; and a plurality of receptors fixed in a space between the microelectrodes to specifically react with a target biomaterial. In particular, a micropattern of a conductive material is formed in the space between the microelectrodes. Accordingly, greater electric field intensity can be obtained compared to a biosensor without micropatterns, thereby concentration of the target biomaterial using dielectric electrophoretic forces can be performed more efficiently. In addition, damage to biomolecules can be prevented by lowering the intensity of a voltage for a dielectric electrophoresis phenomenon and the biosensor can be easily commercialized as a health care sensor for diagnosing diseases.
