more-inScientists from the University of Oxford have developed a synthetic, soft tissue retina that closely mimics the natural retinal process. But a biological synthetic implant is soft and water-based, so much more friendly to the eye environment,” said lead researcher Vanessa Restrepo-Schild from Oxford University. Just as photography depends on camera pixels reacting to light, vision relies on the retina performing the same function. The synthetic, double-layered retina replica consists of soft water droplets (hydrogels) and biological cell membrane proteins. “The synthetic material can generate electrical signals, which stimulate the neurons at the back of our eye just like the original retina,” Ms. Restrepo-Schild said.
