Abstract

We have studied and developed electrophysiological biosensors by MEMS technology. Micro channel arrays (hereafter MCA) integrated with suction holes and electrodes were previously presented for electrophysiological biosensors for the drug screening. This paper proposes novel electrophysiological biosensors with MCA for both batch measurement and multipoint measurement of cell signals based on our previous results. Report on experimental results of feasible study with using developed biosensors will follow the description of design and fabrication of devices.
