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 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) 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 ...

As they have been designed to undergo colorimetric changes that are dependent on the polarity of solvents, the majority of conventional solvatochromic molecule based sensor systems inevitably display ...
