For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory ...

For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called composition). Spectrometers are a type of lab equipment that uses prisms or ...

The UC Davis device exploits the properties of photon-trapping surface textures (PTST), surface modifications that enhance the light absorption capabilities of silicon photodiodes in the near-IR range ...

While standard, bulky spectrometers lose sensitivity in the near infrared (top), this new miniature chip uses specialized surface textures and AI to detect signals that are normally invisible (bottom) ...

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 ...
