Injectable nanoparticles restore light response in blind retinas

An international research team has developed microscopic particles that act as tiny light receptors for blind retinas. Injected into the eye, they settle near retinal nerve cells and, when hit by light, trigger electrical and chemical processes that activate the neurons to send signals toward the brain. The work is still preclinical.

• Nanoparticles are injected into the eye and act as artificial light receptors
• Light triggers electrical and chemical processes in the particles
• Activated retinal neurons send signals toward the brain
• Results come from a preclinical study
