Click-Functionalized Compact Quantum Dots Protected by Multidentate-Imidazole Ligands: Conjugation-Ready Nanotags for Living-Virus Labeling and Imaging

We synthesized a new class of mutifunctional multidentate-imidazole polymer ligands by one-step reaction to produce conjugation-ready QDs with great stability and compact size. Furthermore, combined with strain-promoted click chemistry, we developed a general strategy for efficient labeling of living-viruses with QD probes.
