Photoacoustic spectroscopy approach enables real-time detection of low gas concentrations
A new method for detecting and identifying gases at very low concentrations in real time adds coherent control to quartz-enhanced photoacoustic spectroscopy, which uses a quartz tuning fork to detect gas absorption. Credit: Florian Sterl, Sterltech Optics GmbH Researchers have developed a new method to quickly detect and identify gases at very low concentrations. This new approach, called coherently controlled…

Expanded color gamut with fast-response colorimetric sensor for real-time monitoring
The proposed sensor design incorporates a porous germanium layer (Pr-Ge) that significantly improves the color representation and a nanohole array that increases the responsiveness of the sensor. Credit: Busan University Associate Professor Gil Ju Lee Colorimetric sensors detect changes in the environment by intuitively changing colors, easily visible to the naked eye without the need for additional equipment. Moreover, it…

Glowing proteins enable real-time 3D studies of essential enzymes
Graphical summary. Credit: Nature Chemical Biology (2024). DOI: 10.1038/s41589-024-01758-3 Researchers at the University of California, San Diego School of Medicine have developed a new tool to use organoid models to study the protein kinase C (PKC) enzyme, which plays a critical role in cell growth, differentiation, and survival. Dysfunction of these proteins has been linked to many human diseases, including…
