This Magical-Sounding Nanochip Can Heal Wounds With A Single Touch

The device sits on the skin, and an intense electric field is applied through it, injecting genes into skin cells and turning them into other types of cells to treat diseased conditions.
Scientists, including one of Indian origin, have developed a device that can convert skin cells in the body into any other cell type with just a touch, an advance that may help fix injured tissues, blood vessels and nerves.
"This technology does not require a laboratory or hospital and can actually be executed in the field", Chandan Sen, the director of the Center for Regenerative Medicine and Cell-Based Therapies, told USA Today.
"With this technology, we can convert skin cells into elements of any organ with just one touch". The RNA or DNA is injected into those channels where it takes root and starts to reprogram the cells.
Dr Sen added: "By using our novel nanochip technology, injured or compromised organs can be replaced".
Researchers have developed a groundbreaking new device that can develop new cells within a patient's own body, simply by acting on the skin.
Chicago to file suit against Trump's immigration policies Todd gets reaction from Robert Law, Government Relations Director for FAIR, the Federation for American Immigration Reform. Chicago alone was slated to receive $3.2m from the grant program this year to purchase new police equipment.
In a new study published in Nature Nanotechnology, first author Daniel Gallego-Perez of Ohio State demonstrated that the technique worked with up to 98% efficiently.
This breakthrough technology is the first time cells have been reprogrammed in a live body.
One week after the application of TNT, vascular vessels reappeared.
"This is hard to imagine, but it is achievable, successfully working about 98 per cent of the time".
Lead author Daniel Gallego-Perez says the new technology comprises two elements: the nanotech chip created to introduce reprogrammed DNA into existing adult cells; and a "specific biological cargo" that induces the cells to change from one type to another. Additionally, this technology does away with the need to use viruses as a delivery system for the new cells.
Researchers said the technology itself is small and portable, allowing it to be used outside of a doctor's office or lab. For a long time researchers have tried to come up with a mechanism that could treat and even fix brain injuries. There were no side effects reported with the treatment, which also was used to grow brain cells in mice who suffered strokes. "So this is the beginning, more to come".
The researchers are awaiting approval from the FDA to conduct human trials. Let us know in the comment section below!
