VIDEO: Small robots "swim" through a bulb to deliver drugs



Last Friday, a team led by Max Planck's Institute of Medical Research, published a study on the potential of new ophthalmologic clinical intervention techniques at Science Advances. For teaching purposes, this Wednesday released a video explaining the content that was investigated in graphic form, published in the journal Science.

The study reflects a research work by revolutionary nanobots, made with 3D printers, aimed at improving the treatment of ophthalmic diseases. It is reported there that in a future that is currently far removed, these robots can be used to transport and administer drugs to the human eye and thus prevent the disease.

The microprocessors are 200 times smaller than the width of human hair and have a spiral tail that facilitates the journey through the vitreous jelly. Having said them in numbers of up to 10,000 in eyes taken from pigs, researchers said they could be more efficient and faster eye drops or injections. The survey revealed that they passed through the pig's eye 10 times faster which particles are of the same size.

With models like clamps, they have a slippery coating be able to move without damaging the bulb. 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 effective, it takes a lot of time to get the drug at the heart of the problem.

The most direct viewing of it

One of the most common diseases that require injection into the eye is age-related macular degeneration, caused by diabetes, which prevents blood vessels or determines their abnormal growth.

Elements of the nickel and directed from an external magnetic field, small robots should also be infused but would not cover the entire surface of the eye They will go directly the origin of the disease. Using a live scanner that shows your location, doctors could have one 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 they make it to humans.
