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 proposed sensor design incorporates a porous germanium layer (Pr-Ge), significantly improving color representation, and nanohole arrays that enhance the sensor’s responsiveness. Colorimetric ...

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 ...

(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 ...

(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 ...

Scientists combine organic probes and quantum dots in a new colorimetric sensor to measure oxygen with high resolution. The measurement of the concentration of oxygen is important in a wide range of ...
