Toward Nanoparticle “Night-Vision Goggles”

Optics and Photonics  March 1, 2019 Researchers in China developed ocular injectable photoreceptor-binding upconversion nanoparticles (pbUCNPs). These nanoparticles anchored on retinal photoreceptors serve as miniature NIR light transducers to create NIR light image vision with negligible side effects. In tests they demonstrated that mice with these nanoantennae could not only perceive NIR light, but also see NIR light patterns. According to the researchers the research could be a potential alternative to night-vision goggles, the treatment could help repair certain vision problems and eye diseases…read more.
