The medical world sees another example of science fiction coming true. Scientists have revealed a "breakthrough technology" that repaired cells and organs in mice and pigs with a 90 per cent success rate. Researchers at Ohio State University in the USA have developed a device barely a centimeter wide that is full of tiny microchips called nanochips. The new device is a pad that is placed on the skin. It initiates the process of repairing damaged organs and healing serious wounds. The nanochips "reprogramme" damaged cells to restore them to their functional state. Researcher Dr Chandan Sen said: "With this technology, we can convert skin cells into elements of any organ with just one touch."
The new technology is called tissue nano-transfection (TNT). It is a non-invasive procedure, which means surgeons do not have to cut the body. It works by placing the pad of nanochips over a damaged area of the body. A small electric current then injects DNA into the skin's cells in less than a second. This transforms the cells into building blocks that then regenerate any nearby damaged tissue, such as skin, arteries, or even organs like the liver, lungs and heart. Researchers say it could replace the need for patients needing reconstructive surgery and revitalize organs that are prematurely aging. It could even help repair the brain. Testing will begin on humans next year.
