    摘要: An electrical sensing and stimulation electrode small enough to record intracellular activity within a single living cell. The electrode incorporates a cylindrical chamber with a finely tapered end section. The chamber is evacuated to hold the cell at its tip. Contained within the chamber are piping, circuitry, and controls to provide selected life support environment, stimulation, and continuous sensing of the iternal ionic composition of the captured cell.
