System enables high-performance paramagnetic sensing in portable and space-constrained environments where traditional systems cannot operate.

UC Davis electrical engineers have created a chip-sized device to measure the spectrum of visible and infrared light. The spectrometer-on-a-chip could have a wide range of applications in medicine, ...

An international team of researchers has developed a mid-infrared spectrometer smaller than the diameter of a human hair. With potential applications that range from detecting greenhouse gases to ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240099 discusses an on-chip spectrometer with high performance, low power-consumption and simple control logic. The miniaturized ...

This is a close-up view of the “spectrometer-on-a-chip” technology that could dramatically reduce the size of spectrometers in the future. (Credit: NASA Goddard/Chris Gunn) The Composite Infrared ...

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 ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
