Abstract

A device (10) for measuring electrophysiological properties of a cell membrane of an individual cell comprises a plate (22) provided with at least one opening (58). The opening is bounded by a surface and the surface is modified, such as via heat treatment, to facilitate formation of a gigaseal. A chamber (46) is adjacent to the plate. The chamber is in fluid communication with at least one opening and is adapted to hold an electrically conductive solution. The plate further comprises a first electrode (36) located in the chamber and a second electrode (28) located adjacent to the plate.
