The medical world [seen / sees] another example of science fiction coming true. Scientists have [revealed / revealing] a "breakthrough technology" that repaired cells and organs [on / in] mice and pigs with a 90 per cent [successful / success] rate. Researchers at Ohio State University in the USA have developed a device [barely / bared] a centimeter wide that is full of tiny microchips called nanochips. The new device is a pad that is [placing / placed] on the skin. It initiates the process [if / of] repairing damaged organs and healing serious [winds / wounds] . The nanochips "reprogramme" damaged cells to restore them to their [functional / function] state. Researcher Dr Chandan Sen said: "With this technology, we can convert skin cells into elements of any organ with just [one / once] touch."

The new technology is called [issue / tissue] nano-transfection (TNT). It is a non-invasive [procedure / proceed] , which means [surgeons / surgeries] do not have to cut the body. It works by placing the pad of nanochips over a [damaged / damaging] area of the body. A small electric [currant / current] then injects DNA into the skin's cells in [less / fewer] than a second. This transforms the cells into building blocks that then regenerate [many / any] nearby damaged tissue, such as skin, arteries, or [even / ever] organs like the liver, lungs and heart. Researchers say it could replace the need for patients [needy / needing] reconstructive surgery and revitalize organs that are prematurely aging. It could even help repair the brain. Testing will begin on [humans / human] next year.
