New tiny device may help treat Alzheimer’s and Parkinson’s disease

At Ohio State University, researchers are developing a new design in nanotechnology called Tissue Nanotransfection (TNT), according to The Guardian. The researchers believe it could help treat certain diseases like Alzheimer’s and Parkinson’s disease.

It is a dime-sized silicone chip, and it injects genetic code into skin cells, turning those cells into different cells required for treating a disease or conditions. This new device reprograms skin cells, and could represent a breakthrough in repairing injured or aged tissue.

According to the researchers at Ohio State University, the tiny device sits on the skin of a living body. Then, an intense focused electric field is applied across the device, which allows it to deliver genes to the skin cells beneath it, turning it into different cell types.

This new development is waiting to get approved by the Food and Drug Administration for human trials. So far it has only been formally tested on mice with injured legs; however, in three weeks it completely restored blood flow in the mice.

Chandan Sen, director of the center for Regenerative Medicine and Cell based Therapies, told USA today, “For example, the technology restored brain function in a mouse who suffered a stroke by growing brain cells in its skin.” Sen also said, “This technology does not require a laboratory or hospital and can be actually executed in the field. Less than 100 grams to carry and will have long self-life.”

Nanotechnology is a categorized in either science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Nanomachines are typically extremely small devices created to make existed atoms to make them something else.
