INSTRUMENT AND METHOD FOR MEASURING ACTION SIGNAL OF BIOLOGICAL SAMPLE

WIPO Patent Application WO/2003/096002

A1

An instrument for measuring an action signal of a biological sample comprises a measurement chamber (A) filled with a liquid to be measured and containing a biological sample, a porous insulating substrate (5) having a measurement electrode (1) at least on one side thereof, and a transport device (8) for transporting the liquid in the measurement chamber (A) from the measurement electrode (1) side to cause the liquid to pass the porous insulating substrate (5). Since the biological sample contained in the liquid is trapped by the measurement electrode (1) by operating the transport device (8), the action signal of the biological sample can be measured through the measurement electrode (1). Thus the instrument measures the action signal generated by a biological sample simply and quickly with high precision.
