Abstract
One of the indispensable tools of electrophysiology is patch-clamp recording, which enables direct observation of ionic transport through cellular membranes. It is an invaluable research tool, providing experimental information related to cellular electrical metabolism, as well as various pathological conditions. While the inventors of patch-clamp recording subsequently became Nobel laurates [1], still it can be considered as one of the most complicated experimental setups, due to the difficulty in puncturing cells using capillary microelectrodes with extreme precision. The throughput of the measurement is also considerably low. Thus, automatized planar patch-clamp systems depending on automatic suction of cells using special chips have emerged, considerably increasing the throughput of electrophysiological measurements for about a decade [2]. However, they are generally restricted to be used only with cultured cells, while they have a poor applicability when isolated cells are considered. Real-time observation of the cells for quality assessment, in terms of the measurement, is also not possible.
