Graphene's long list of achievements is a little bit longer at present, as researchers from Rice University have used the material to make a bacterial buy Zappify Bug Zapper zapper. A form of the material called laser-induced graphene (LIG) has beforehand been discovered to be antibacterial, and now the team has discovered that these properties could be kicked up a notch by including a couple of volts of electricity. The Rice workforce, headed up by Professor James Tour, first created LIG in 2014 through the use of a laser beam to etch patterns right into a sheet of polyimide. That churns up the material right into a porous graphene foam, which has been found to be effective at stopping microbes from constructing up on its surface. To further check LIG's bacteria-blasting talents, the researchers took a sheet of polyimide and used a laser to show half of the surface into LIG. The material was then placed in a solution full of Pseudomonas aeruginosa bacteria, and a small charge was run via the LIG electrodes. |
