Not Hair Loss News – Micro-Robots Created to Carry Drugs Into the Bloodstream

Snippet from the article:

Small enough for injection without leaving a wound, new microrobots could revolutionize the way modern medicine treats certain hard-to-reach areas of the body. The eyes and brain are extremely tricky places for surgeons, and a non-invasive solution to certain ailments has long been sought. The impediments to this are numerous, however, and range from producing to controlling to excreting any tiny agents that might be up to the job.

Now Chinese University researchers say they’ve created a working microbot for internal use, a cage-like structure just 100 microns long by 40 microns wide. Its inventors coat the cage shape in a thin layer of nickel, giving it the magnetic properties they require to guide it through to body after insertion. The electromagnetic field used to guide the little “robot” can push them through the body with extreme accuracy. In tests, the researchers were able to show that their robot successfully delivered a drug payload to the predetermined target cells.

They are testing with rabbits and mice for now, but hope to have human trials soon.
