VIDEO: Small robots "swim" through the eyeball to give medication

Last Friday, a team led by scientists from the Medical Research Institute Mak Planck from Germany, published in the Science Advances study on the possibilities of new techniques of ophthalmic clinical intervention. To distribute it in a didactic way, a video was released this Wednesday that explains what was explored in graphic form, published in the journal Science.

The study reflects the research work done by revolutionary nanobots made by 3D printers, with the aim of improving the treatment of eye diseases. It is stated here that in the future which at this moment seems to be far away, these robots can be used for the transport and administration of drugs in the human eye and thus prevent disease.

"Micropopulders" are 200 times smaller than the width of the human hair and have a spiral tail, which makes it easier to travel through the glass jelly. After testing them in a number up to 10,000 in pig's eyes, the researchers said they could be more efficient and faster than eye drops or injections. The investigation revealed that they had passed through the pig's eye 10 times faster which particles of the same size.

Modeled as crescent, have a slip coating so that they can move without damaging the eyes. They would introduce drugs and could be used to treat glaucoma or diabetic retinopathy.

Currently, intravitreal injection or eye drops are the most common. While they are effective, they take a long time to get the drugs to the focus of the problem.

His fastest projection

One of the most common injuries in the eye is macular degeneration, caused by diabetes, which blocks blood vessels or determines their abnormal increase.

Facts from nickel and directed by an external magnetic field, small robots should also be injected, but they would not cover the entire surface Eye They would go directly on the origin of the disease. By using a live scanner that points to your position, doctors can have a sufficient control transfer them to all necessary guidelines.

They have not yet been tested on living beings, for which animals will first of all use before they do it in humans.
