Abstract
A simple circuit is described, which, in conjunction with an electrometer and a digitally-controlled hydraulic microdrive, automatically advances a microelectrode through the bathing solution and halts the microelectrode when a cell is impaled. The distance between initial contact with the cell membrane and cell penetration (1-5 μm for rabbit corneal epithelium) is dependent upon the physical characteristics of the cell and microelectrode, and can be optimized by empirical adjustment.
