Injectable nanoparticles make blind retinas respond to light in preclinical study
An international research team has developed microscopic particles that can make blind retinas respond to light.
An international research team has developed microscopic particles that can make blind retinas respond to light.
The short version
- The particles act as tiny light receptors.
- Researchers inject them into the eye, where they settle close to nerve cells in the retina.
- When light hits the particles, it triggers electrical and chemical processes that can activate the nerve cells and prompt them to send signals toward the brain.

Why it matters
In experiments with blind mice, the researchers were able to detect light-induced signals in the visual cortex of the brain and observe behavioral responses to light.
