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 ...

Reliable colorimetric analysis technologies have been widely praised for their highly sensitive and selective responses towards various contaminants in environmental monitoring. In principle, the ...
