In Situ Colorimetric Quantification of Silver Cations in the Presence of Silver Nanoparticles

Silver ions (Ag+) can be quantified in situ in the presence of AgNPs by using a colorimetric sensing probe (3,3′,5,5′-tetramethylbenzidine). Interestingly, it also enables detection of the Ag+ adsorbed on the AgNP surface. This is relevant to design new methods to make AgNPs while ensuring the total...

Summary:Silver ions (Ag+) can be quantified in situ in the presence of AgNPs by using a colorimetric sensing probe (3,3′,5,5′-tetramethylbenzidine). Interestingly, it also enables detection of the Ag+ adsorbed on the AgNP surface. This is relevant to design new methods to make AgNPs while ensuring the total reduction of Ag+.
