A type of the fabric called laser-induced graphene (LIG) has previously been found to be antibacterial, and now the workforce has found that those properties may be kicked up a notch by including a couple of volts of electricity. The Rice team, headed up by Professor James Tour, first created LIG in 2014 by using a laser beam to etch patterns into a sheet of polyimide. That churns up the fabric right into a porous graphene foam, which has been found to be efficient at stopping microbes from building up on its floor. To additional test LIG's micro organism-blasting talents, the researchers took a sheet of polyimide and used a laser to turn half of the floor into LIG.
