Retina-inspired carbon nitride-based photonic synapses for selective detection of UV light

Researchers at Seoul National University and Inha University in South Korea have developed photo-sensitive artificial nerves that emulated functions of a retina by using 2-dimensional carbon nitride (C3N4) nanodot materials. Further, through the photo-sensitive artificial nerves which selectively detected ultraviolet (UV) light and processed the information, a smart window platform was demonstrated for in-situ modulation of exposure to UV rays depending on the degree of UV exposure and risk.
