For the first time, scanning electron microscopy has been used to investigate the binding of gold nanoparticles to fingermarks placed on nanoporous surfaces. The results show that gold nanoparticles, under standard MMDII conditions, bind preferentially to latent fingermark ridges on nonporous surfaces. Variation in surfactant concentration influences background development but does not affect the binding of gold nanoparticles to the ridges, while pH variation influences the binding to ridges but leaves valley regions unaffected.
