At Nagoya University, researchers have engineered gallium-doped zinc oxide nanosheets that allow a single pixel to perceive the full range of visible color — a feat that mirrors the architecture of the human eye itself. For decades, cameras have reconstructed color indirectly, pixel by pixel, through a patchwork of filters that infer what neighboring sensors could not see. This breakthrough, published in ACS Nano, suggests that the long detour between how machines capture light and how living beings experience it may finally be closing.
