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 ...

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 ...

(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 ...
