From: Rapid visualization of latent fingermarks using gold seed-mediated enhancement
Optical images of using Au seed-mediated enhancement to visualize the latent fingermarks at different conditions with increasing: a the incubation time (5, 15, and 30 min) of LBA-Au NPs, b the concentration (132, 264, and 396 µL) of LBA-Au NPs, c the incubation time (5, 15, and 30 min) of Au+-complex solution and d the concentration (132, 264, and 396 µL) of Au+-complex solution. The upper frame means that the used conditions in this study. In a–d tests, only one parameter is changed in each test keeping the rest of the conditions analogous to the upper frame
