Key Points:
- An international research team led by Prof. Dr. Sedat Nizamoğlu at Koç University has developed a next-generation, ultra-thin, wireless retinal stimulation technology using near-infrared light to safely treat retinal degenerative diseases causing vision loss.
- The novel photovoltaic nano-assembly combines zinc oxide nanowire arrays with silver–bismuth–sulfide nanocrystals, enabling precise electrical stimulation at low light intensities well below ocular safety limits without damaging eye tissue.
- Testing on rat retinal models showed strong, repeatable neuronal responses with no cellular toxicity or stress, and the device demonstrated long-term biocompatibility and negligible temperature increase during operation.
- Unlike current bulky retinal implants requiring visible light and external
