AI Summary

Researchers have created microscopic particles that act as artificial light receptors for blind retinas. The particles are injected into the eye and settle near retinal nerve cells. When light strikes the particles, they trigger electrical and chemical signals that activate the nearby nerve cells. The activated nerve cells then send signals toward the brain, potentially restoring light perception. This preclinical study demonstrates a new approach to treating blindness by enabling the retina to respond to light.
