Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient ...

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food ...

Resting on a fingertip, this miniature sensor replaces bulky laboratory equipment by using photon-trapping surface nanostructures and artificial intelligence (AI) to accurately analyze disease, check ...
