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 ...

With the worldwide coronavirus top of mind, scientists continue to develop new technology that can provide evidence-based guidance to quickly and accurately pinpoint potential environmental dangers.

The ongoing COVID-19 pandemic has shown that the world needs technology that can quickly and accurately identify invisible dangers, including harmful substances or airborne environmental pollutants.

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 ...
