An international research team has developed light-sensitive nanoparticles that can be injected into the eye, aiming to help restore some visual signals in individuals with retinal degeneration, especially in cases involving deterioration of light-sensitive cells such as retinitis pigmentosa. Experiments showed that these particles, made from graphene carbon nitride with a diameter of about 300 nanometers, were able to activate nerve cells in the retinas of affected mice and transmit light signals to the brain, although complete vision or fine details were not restored. The study, published in the journal Nature Biomedical Engineering, indicates that the technique is still in its early stages and requires further research to ensure safety before it can be used in humans. However, it presents a potential alternative to current vision loss treatments such as gene therapy or electronic devices that require surgery.
