Abstract
A detecting chip () comprising a body () and a frame () both detachable from each other. A large number of projecting pin electrodes () are arranged in a matrix inside the body (). Oligonucleotide consisting of different gene sequences is fixed to the pin electrode (). A common electrode is so disposed in a recess () in a frame () as to be out of contact with the pin electrodes (). A DNA sample is placed in the recess (). By applying a voltage between the common electrode and the pin electrodes (), a current is detected to detect a hybridized two-strand DNA, thus analyzing a gene DNA.
