Using a strategy that should be applicable to many fluorescent dyes, chemists have created the brightest-ever fluorescent materials. The approach combines commonly available cationic dyes and a ...

Adsorption with clay materials, activated carbon, iron oxide and natural materials such as coffee grounds, has also been used before and exhibit high cationic dye uptake, exchanging ions or forming ...

Flexible synthetic skins use hydrogel arrays to mimic cephalopod camouflage through autonomous color and pattern shifts for soft robotics and wearables.

SMILES perfectly transfer the optical properties of dyes to solids, are simple to make by mixing cationic dyes with anion-binding cyanostar macrocycles, and work with major classes of commercial ...
