  • Biological cell test method and apparatus
    Patent number: 6828807
    Abstract: A biological cell test method and apparatus employs a conventional perforated cell carrier which has a plurality of holes. Each hole has two metal electrodes. A cell is disposed in the hole to contact the two electrodes. The electrodes are connected to electric current or voltage. The electric current or field flows from one electrode through the cell to another electrode. Through the inherent impedance, inductance or capacitance of the cell, the presence or property reactions of the cell may be detected.
