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

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 ...

When foods like fish, meat, and cheese decompose, they release a variety of low molecular weight organic nitrogen compounds known as biogenic amines (BAs). While the body uses BAs in small amounts in ...
