Diazo transfer at polydopamine – a new way to functionalization

Polym. Chem., 2014
The possibility of introducing azido functions onto polydopamine by diazo transfer making use of existing aminoethyl moieties was verified at polydopamine-coated magnetite nanoparticles. The resulting azidofunctionalized Fe3O4@polydopamine nanoparticles serve as a magnetic nano-platform for the introduction of interesting applicatory functions by click-
