Retinal Chip News Today : Breaking News, Live Updates & Top Stories | Vimarsana

Retinal prostheses offer viable vision restoration therapy for patients with blindness. However, a critical requirement for maintaining the stable performance of electrical stimulation and signal transmission is the biocompatibility of the electrode interface. Here, we demonstrated a functionalized electrode-neuron biointerface composed of an annealed graphene oxide-collagen (aGO-COL) composite and neuronal cells. The aGO-COL exhibited an electroactive 3D crumpled surface structure and enhanced the differentiation efficiency of PC-12 ​cells. It is integrated into a photovoltaic self-powered ...

To get vision restoring microchip implants that are considered revolutionary. more from the bbc's fergus walsh. >> reporter: just six weeks ago, chris james was totally blind. now he can perceive light. this box powers his implant but it's what's under his scalp which is amazing. this x-ray shows the computer processor above his ear linked by a cable to the implant behind his retina. the wafer-thin chip is just three millimeters square. now he can perceive light and even the outline of shapes. chris is one of thousands of people in the uk with retinitis pigmentosa. the light processing cells i...
