Abstract:

Gold nanoparticles, AuNPs, capped with mercaptocarboxylic acids followed by silver pptn. develop latent fingermarks on paper as high quality "neg." impressions. This effect stems from hydrogen bonding between the carboxylic group and the paper cellulose and may improve the yield of latent fingermarks since the results are less dependent on sweat compn.
