VIDEO: Small robots "swim" through a globe to administer drugs



Last Friday, a team led by researchers at the Max Planck Institute for Medical Research in Germany published a study in Science Advances on the possibility of new ophthalmic clinical intervention techniques. For a diffusion in a teaching style, a video was released this Wednesday, explaining what was researched in graphic form, published in the journal Science.

The study reflects a research done by revolutionary nanobots made with 3D printers in order to improve the treatment of eye diseases. It is stated that in a future that is now far away, the robots could be used to transport and administer drugs in the human eye and thus prevent diseases.

"Micropopulters" are 200 times smaller than the width of human hair and has a spiral tail that facilitates vitreous jelly journey. After testing them in up to 10,000 pig eyes, the researchers said they could be more efficient and faster than eye drops or injections. The survey showed that they passed through the pig's eyes 10 times faster what particles of the same size.

Model as tadpole, they have a slippery slippage so you can move without affecting the eyeball. They would introduce drugs and could be used to treat glaucoma or diabetic retinopathy.

Currently, intravitreal injections or eye drops are the most common techniques. While they are effective, they take a long time for the drug to get to the center of the problem.

The most immediate projection

One of the most common diseases requiring eye injection is age-related macular degeneration, caused by diabetes, which blocks blood vessels or causes them to grow abnormally.

Facts of nickel and directed by an external magnetic field, small robots should also be injected, but would not cover the entire surface of the eye They left direct at the origin of the disease. Using a live scanner indicating your position, physicians may have a sufficient control to move them in all the necessary directions.

They have not yet been tested on living beings, for which the animals will be used first before making them to humans.
