Scientists at Ohio State University have discovered a way to use silicon chips embedded with technology to heal human tissue, known as tissue nanotransfection.

The chip injects genetic code into the skin cells, effectively reprograming the cells and enabling them to heal. According to Engadget, the researchers have also reprogramed skin cells into vascular cells. In one test on a mouse with an injured leg, the team was able to restore blood flow to the rodent’s appendage within two weeks. The breakthrough is reportedly the first time cells have been reprogrammed in a living body.
