Fig. 10From: Rapid visualization of latent fingermarks using gold seed-mediated enhancementOptical images of using Au seed-mediated enhancement to visualize the latent fingermarks on a plastic and b glass. The plastic is the surface of commercial CD. The glass is general glass slide. Both samples used the same experimental conditions. The treatment time of LBA-Au NPs (200 µL) and Au+-complex solution (300 µL) for fingermarks were 5 and 3 min, respectivelyBack to article page
