DETECTION PART FOR INTERACTION BETWEEN SUBSTANCES UTILIZING CAPILLARY PHENOMENON, METHOD USING SAME, AND SUBSTRATE FOR BIOASSAY

摘要

PROBLEM TO BE SOLVED: To provide a novel technique for sending a sample aqueous solution into a minute reaction region to freely perform the higher-order structural adjustment, movement, and fixation of a substance, and the removal of an unnecessary substance or the like. SOLUTION: This detection part for the interaction between substances comprises a reaction region 2 for providing a place of the interaction between the substances; at least a pair of counter electrodes E1and E2opposedly arranged so as to be capable of applying an electric field to the medium such as an aqueous solution, a gel or the like housed in the reaction region 2; a suction hole 3 for sending the medium containing the substances into the reaction region 2 by a capillary phenomenon and an outside air communication hole 4. This detection part is used in a substrate for bioassay such as a DNA chip or the like. COPYRIGHT: (C)2005,JPO&NCIPI
