The authors here described a visual detection strategy employing 4-amino-3-hydrazino-5-mercapto1, 2, 4-triazole (AHMT) functionalized gold nanoparticles (AuNPs) to detect kanamycin (KA) in various samples. The AHMT with mercapto group was self-assembled onto the surface of AuNPs and the AHMT functionalized AuNPs (AHMT-AuNPs) aggregated when ICA existed owing to the hydrogen-bonding interaction between KA and AHMT. As a result, the color of the AHMT-AuNPs solution changed from wine red-to-deep purple with the increasing concentration of KA. Taking advantage of the hydrogen-bonding interaction, ...
