VIDEO: & # 39; swim & # 39; small robot through eyeballs to manage medicines


Last Friday, a team led by scientists from the Max Planck Institute for Medical Research, Germany, published in Science Progress a study of possible new techniques of ophthalmological clinical intervention. For the dissemination in a didactic manner, on Wednesday a video explaining what was examined in the form of a graphic, which was published in the journal Science, was released.

This study reflects research work made from revolutionary nanobots, made with 3D printers, with the aim of improving the treatment of eye diseases. It states that in the future, which currently looks far, the word robot can be used to transport and manage drugs in the human eye and thus prevent disease.

The & # 39; micropopulders & # 39; is 200 times smaller than the width of a human hair and has a spiral tail that facilitates travel through vitreous jelly. After testing them in quantities of up to 10,000 in the eyes taken from pigs, the researchers said they could more effective and faster from eye drops or injections. Investigation revealed that they passed the pig's eye 10 times faster what particles are of the same size.

Modeled as tadpoles, they have slippery layer to be able to move without damaging the eyeball. They will introduce drugs and can be used to treat glaucoma or diabetic retinopathy.

At present, intravitreal injections or eye drops are the most common technique. While they are effective, they need a lot of time for drugs to reach the focus of the problem.

The fastest projection

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

Facts about nickel and directed by an external magnetic field, small robots also need to be injected but they will not cover the entire surface from their eyes they will leave directly to the origin of the disease. Using a live scanner that shows your position, the doctor can have it enough control to move it in all necessary directions.

They have not been tested in living things, where animals will be used in the first place before doing so in humans.
