Some of the diseases of the retina cause the degeneration of photoreceptors, light-sensitive particles that stimulate neurons to function, their malfunction can even cause blindness.
A group of scientists from the Italian Institute of Technology have developed the first liquid retina prosthesis that will alleviate the dysfunction of the aforementioned photoreceptors.
The results observed in the experiments show that these photoreceptors really work as expected by stimulating the neurons that are not damaged, working in the same way as the photoreceptors.
The fact of being a liquid prosthesis implies much less aggressive surgery since the procedure consists of using micro-injections with these nanoparticles, directly under the retina where they are trapped.
As you can see, nanotechnology will be one of the disciplines that will surprise us the most in the coming years, not only in medicine but in many other fields.
