They develop a technology that restores the lost vision of golden nano
Researchers at the University of Brown (United States) developed a The technique that was able to restore vision in animals with diseases in the retinaBy injecting golden nanoparticles.
The process consists of Enter small golden particles into the eye To “look” in the internal cells of the retina, and after injecting a liquid solution for nanoparticles, researchers use infrared laser light with patterns to show different shapes on the retina.
The study published in ACS Nano Magazine This explains “this new approach Use the nanoparticles that are injected directly into the retina to avoid damaged light receptors. When the infrared light focuses on the nanoparticles, it generates a small amount of heat that stimulates dual -electrode and extremely emotional cells how the optical receptors ’pulses do. “
Therefore, given that disturbances such as macular degeneration mainly affect light receptors, This strategy has the ability to restore the lost vision. However, this treatment is still in an experimental stage, but in the face of the future, It can be an effective alternative For those who suffer from eye diseases.
“This is a A new type of retinal synthetic Who has the ability to restore the vision that the retinal degeneration lost Without the need for a complex surgery or genetic modification. In addition, he believes, “this technique can Transfer the treatment forms For degenerative retinal diseases. “
Can it be tested in humans?
For human use, researchers imagine A system that combines nanoparticles and a laser system installed on glasses. Glass glasses will collect data from the image from the outside world and will use them to control the formation of infrared laser patterns, and in this way, laser pulses It will motivate nanoparticles in the popular eye networks, allowing them to see.
On the other hand, the study indicates that “since the nanoparticle solution covers the entire retina, the new method can cover the entire optical field. Since nanoparticles respond to the nearby infrared light, unlike visible light, the system does not necessarily interfere with the remaining vision that a person can maintain.”
However, the researchers assert that it is necessary Doing more research before trying this approach to a clinical environmentAlthough initial research indicates that it is possible.
