Inventor: INUZUKA HIROMASA
IPC: G01N21/27
Filed: 2002-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a DNA sensor device capable of detecting the presence of a biochemical reaction with high precision without an effect of nonsingular adsorption, etc., caused by an impurity, and without using a fluorescent labeling, etc.   <P>SOLUTION: The DNA sensor device is formed by a plane constituted of the tip planes of center projections in hollows formed by etching and removing a surface into ring shapes, and is provided with a measuring part in which ligands are arranged and fixed. A substrate provided with a metal film coating over the hollows and an electric pole plate are oppositely arranged, and a high voltage is applied between them wherein the higher voltage is impressed to the substrate. After a reacting solution containing the ligands flows between the substrate and the electric pole plate while impressing the voltage, the voltage is inverted and the measuring part is cleaned, thereafter irradiation light from a light source irradiates the rear face side of the substrate. At this time, the presence of the biochemical reaction of the reference and the ligands is measured by utilizing a surface plasmon resonance.  <P>COPYRIGHT: (C)2004,JPO
