Nanochip could heal injuries or regrow organs with one touch, say researchers

A tiny device that sits on the skin and uses an electric field to reprogramme cells could be a breakthrough in the way we treat injured or ageing tissue

A novel device that reprogrammes skin cells could represent a breakthrough in repairing injured or ageing tissue, researchers say.

The new technique, called tissue nanotransfection, is based on a tiny device that sits on the surface of the skin of a living body. An intense, focused electric field is then applied across the device, allowing it to deliver genes to the skin cells beneath it - turning them into different types of cells.
