Development of System For Cell Fusion Detection

Cell fusion device is an artificial equipment which fuses electrically two types of cells fed from the respective micropump to the fusion chamber by electric pulses. In this case, the detective sensor of flowing cell, along with passage, is required to control the time of pulses applied to cell and the injection of cells which are fed from inlet to micropump. There are two methods of detection of flowing cell; optical, impedance method. The difference of output for optical sensor is about 426mV for 805nm wavelength. about 37mV for 665nm wavelength. In impedance method, sensor output is 132.33mV at middle point and 117.10mV at edge point in the channel. Experimental results show that the optimal frequency range of sensor output is Iron 50Hz to 400Hz.
