We present a high-throughput label-free electrical-impedance spectroscopy (EIS) platform composed of a 96 × 96 microelectrode array for counting and analysis of breast tumor cells (MCF-7). These Auelectrodes are densely packed within a 3.5 mm × 3.5 mm interrogation region. Each Au-electrode has an e...
