Scientists create a tiny robot that can draw through the eyes



Scientists create a tiny robot that can draw through the eyes

German, Chinese, and Danish scientists have developed a nano-sized robot that can damage eyes for the first time without damage, and can be used as a minimally invasive tool for accurate drug delivery.

The study, published on Science Advances on Friday, described the vehicle in a spiral shape that is 200 times smaller than the human hair diameter and even less than the bacterial breadth.

According to a study with a slippery coating, the robot can easily move through dense tissue in the eye.

"We apply a layer of liquid found in a carnivorous pitcher plant that has a peristome in the surface of the slate to catch insects," said Wu Zhiguang, research director at the Max Planck Intelligent Systems Institute in Germany. .

"It's like a teflon pans coating, this slick coating is crucial for the efficient operation of our robot inside the eye, as it reduces the bond between the biological protein network in vitrified materials and the surface of our nanoparticles," Vu said.

The researchers tested their nano-hellicion in the eyes of broken pigs. They injected tens of thousands of spiral robots with a bacterial size in the glassy humor of the eye.

Using the surrounding magnetic field that rotates nano-helices, they fly to the retina.

"We want us to use our nanosystems as tools for minimally invasive treatment of all kinds of diseases, where problem areas are difficult to reach and surrounded by thick tissue," said Max Planck researcher Qiu Tian, ​​one of the Relevant study authors said to Xinhua.

The workshop was attended by the University of Stuttgart, the Maxi Planck Medical Research Institute in Heidelberg, the Harbin Institute of Technology in China, the University of Aarhus in Denmark, and the University of Tubingen Eye Hospital.
