Nanocarrier-Based Biological Fluorescent Probes for Simultaneous Detection of Ketamine and Amphetamine in Latent Fingermarks

Nanocarrier-based biological fluorescent probes for ketamine and amphetamine have been prepared by conjugating red and green fluorescent nanoparticles (150-nm-sized) with anti-ketamine and anti-amphetamine antibodies, respectively, with the assistance of carbodiimide/[Formula: see text]-hydroxysuccinimide. Biological fluorescent probes for ketamine and amphetamine could simultaneously detect these two drugs within a single fingermark by one-step...
