Improvement in fingerprint detection using Tb(III)-dipicolinic acid complex doped nanobeads and time resolved imaging

Highlights • Tb dipicolinic acid complex doped silica nanobeads as a fingerprint powder. • Functionalized the surface to increase lipophilicity for selective binding. • Optimised doping efficiency of complex into nanobeads. • Utilised time resolved imaging to successfully detect latent fingerprints....
