In the design of high-throughput cell electrofusion chip,microelectrode array mode is used to increase the amount of microelectrodes,which make the cell electrofusion chip develop to high-throughput, high-efficiency and high-integration lab on a chip. Short distance between a pair of electrodes reduces the requirement of electrofusion voltage and hence the manufacture difficulty of signal source, which also improves the security during the fusion process. Micro-electrode shape and fusion signal are optimized to improve the fusion efficiency. Appropriate fabrication technique and material are chosen to improve the reliability of chip, the electric and biochemical performance.
