Scientists have been trying to replace retinas in otherwise healthy eyes to help people suffering from diseases like retinitis pigmentosa. Unfortunately, earlier efforts were only able to use rigid, hard materials, which are very different from the natural retina. A researcher at Oxford University, however, has created a synthetic retina made of biological materials to better match natural human tissues. The study, titled "Light-Patterned Current Generation in a Droplet Bilayer Array" was published this April in Scientific Reports.
