ABSTRACT:
A detecting chip (2) comprising a body (5) and a frame (4) both detachable from each other. A large number of projecting pin electrodes (10) are arranged in a matrix inside the body (5). Oligonucleotide consisting of different gene sequences is fixed to the pin electrode (10). A common electrode is so disposed in a recess (8) in a frame (4) as to be out of contact with the pin electrodes (10). A DNA sample is placed in the recess (8). By applying a voltage between the common electrode and the pin electrodes (10), a current is detected to detect a hybridized two-strand DNA, thus analyzing a gene DNA.
