The cell membrane, which contains a hydrophilic exterior and a hydrophobic interior, opens and closes ion channels like a water faucet and converts a physicochemical stimulus into an electrical signal that is then transmitted to cells. Until recently, the limited ability of an artificial cell membrane structure to only last a maximum of five days has been a hurdle.
