Patent ID: 8329116

Claim:
A measuring chip for a biologically specifically reactive substance in which an alternating current is applied to electrodes, the measuring chip comprising: two substrates; a spacer coupled to and disposed between the substrates; at least one flow path extending through the spacer, the substrates and the spacer comprising the flow path, the flow path having a hollow configuration and having a first aperture end and a second aperture end; a sample deposition part in which a sample is deposited, the sample deposition part provided in the spacer and coupled to the at least one flow path, the sample deposition part having a first open end and a second open end and being independent from the first aperture end and the second aperture end, the first open end being connected with the first aperture end; and a pair of electrodes to which an electric field is applied, the pair of electrodes arranged within the at least one flow path, wherein: an angle A is provided in the spacer between the first open end and the first aperture end, the angle A is more than 90° and no more than 180°, and an angle B is provided in the spacer at the second open end, the angle B is more than 0° and less than 90°.
