Research at the Italian Institute of Technology suggests a way to make higher-quality, more biocompatible retinal implants by integrating living neural cells with a soft organic polymer semiconductor. It could lead to a retinal implant that produces much clearer vision.
The researchers grew neural cells in a petri dish directly on top of the polymer. Light shined on the polymer activates the photodiodes, which stimulate individual neurons… read more
