Nick Stone discusses some of the many ways in which light can be used for diagnostic and therapeutic applications ...

In order to determine the spectral characteristics of the material (for example, the chemical composition at each point), we ...

In a new study, researchers demonstrate long-term, non-invasive monitoring of blood sodium levels using a system that combines optoacoustic detection with terahertz spectroscopy. The paper is ...

A study in Nature Metabolism uses a depth-selective variant of Raman spectroscopy to probe glucose levels specifically in the skin vasculature, and thereby achieves improved glucose sensing in humans.

We identified a rhodol bearing a hydroxymethyl group (HMDER) as a suitable scaffold for designing fluorescence probes for various hydrolases. HMDER shows strong fluorescence at physiological pH, but ...
