Electroporation machine. Researcher placing a sample holder in an electroporation machine, a device designed to apply an electrical field to cells for chemical or genetic modification. The electric field increases the permeability of the cell membrane, allowing new genetic material or drugs to enter the cell. Introducing new DNA is a process called transfection. Photographed in a biomedical research laboratory.
