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 ...

The basic working principle of colorimetric sensing is colorimetry, which is a visible change in color that results from a chemical interaction between the sensing/detecting material and the target ...

A collaboration of researchers in Japan has developed a sensor for volatile organic compound (VOC) detection. Their manufacturing method allows for fine-tuning of SnO2 nanocrystal and pore sizes.

(Nanowerk Spotlight) Researchers from the Central University of Kerala, India, have developed a point-of-care, portable, rapid, and cost-effective test for clinical diagnosis of sodium, which uses a ...

(Nanowerk Spotlight) Chameleon-like adaptive camouflage is based on structural colors that have evolved in Nature to help animals like cephalopods and certain birds and fish to modify their colors to ...

Volatile organic compounds (VOCs) are a collection of compounds characterized by their high vapor pressure and low water solubility – a combination of properties that allows them to vaporize into the ...

International Gas Detectors Ltd (IGD) is proud to present the launch of a new range of PID (VOC) fixed detectors, in addition to its latest range of portable VOC detectors. These are important ...

Volatile organic compounds (VOCs) are a group of carbon-based chemicals with low evaporation or vaporization points. Some VOCs are harmful to animal or environmental health so sensing these gasses is ...
