An international team of scientists has invented nanorobots that are so small that they can penetrate the eyeball without damaging it. They can be used as a tool for the treatment and delivery of drugs with minimal disruption to the body..
In a published study, the devices are 200 times smaller than the diameter of a human hair, and even smaller than the width of a bacterium. The unique properties of nanorobots are provided by a special coating that allows them to move freely through the eye tissue. This feature, together with the helical motor, helps to minimize adhesion between the vitreous biological network and the surface of the device..
In tests on pig eyes, scientists introduced tens of thousands of nanorobots, which, under the influence of a magnetic field, successfully reached the retina. The researchers plan to use the invention as a tool for minimally invasive treatment of all types of diseases, where the problem area is surrounded by dense tissue and is difficult to access..
Scientists from the German University of Stuttgart, the Institute for Medical Research named after V.I. Max Planck in Heidelberg, Harbin Institute of Technology in China, Aarhus University in Denmark and the University of Tübingen Eye Clinic.
Chinese scientists are also actively working in the direction of flexible robotics. Inspired by the T-1000 from «Terminator», they began to create a robot with liquid metal that can independently change shape under the action of stress.
