Fundamental study of pulse electric field effects on hela cell cultured over extracellular matrix protein micro-patterned surface

Electroporation (EP) is a method of controlling cell function by using pulses of electrical fields to create pores through cell membrane and causes other substance around it to be absorbed into the cell. This method has led to a variety of medical applications, particularly in cell studies. In th...
