Antibacterial

​Every day, dairies dispose of milk that for one reason or another is deemed unfit for human consumption. A Los Angeles-based startup by the name of Mi Terro is taking some of that milk and using it to create T-shirts, that reportedly have some big advantages over regular cotton Tees.

Bacteria are a huge problem in hospitals, where colonies can build up on instruments and cause potentially fatal infections in vulnerable patients. Now, researchers at Aston University have developed a new type of antimicrobial material that’s made using a centuries-old stained glass technique.

​Look around any hospital, and you'll see plenty of hand-sanitizer dispensers. Unfortunately, not everyone uses them, and their germs can spread rapidly on commonly-touched surfaces such as door handles. With that in mind, a University of Leeds spinoff company has created bacteria-killing door pads.

Researchers from Rice University have used graphene to make a bacterial bug zapper. A form of the material called laser-induced graphene (LIG) has previously been found to be antibacterial, and now the team has found that those properties can be kick up a notch by adding a few volts of electricity.
