Colorimetric detection of Cu2+ based on the formation of peptide–copper complexes on silver nanoparticle surfaces
We developed a colorimetric method for the rapid detection of copper ions (Cu2+) in aqueous solution. The detection of Cu2+ is based on coordination reactions of Cu2+ with casein peptide-functionalized silver nanoparticles (AgNPs), leading to a distinct color change of the solution from yellow to re...
