An Artificial Photoreceptor in the Eye
May 1, 2018 | Terry Sharrer
Scientists at Fudan University in Shanghai have created an artificial photoreceptor that restored vision in blind mice. They report: “We develop artificial photoreceptors based on gold nanoparticle-decorated titania nanowire arrays, for restoration of visual responses in the blind mice with degenerated photoreceptors. Green, blue and near UV light responses in the retinal ganglion cells (RGCs) are restored with a spatial resolution better than 100 µm. ON responses in RGCs are blocked by glutamatergic antagonists, suggesting functional preservation of the remaining retinal circuits. Moreover, neurons in the primary visual cortex respond to light after subretinal implant of nanowire arrays.” MORE
