Synthesis of mussel-inspired polydopamine-gallium nanoparticles for biomedical applications.

To established a simple, controlled and reproducible method to synthesize gallium (Ga)-coated polydopamine (PDA) nanoparticles (NPs). PDA NPs were synthesized in alkali medium with posterior Ga shell formation due to ion chelation on the NP surface. The obtained results with energy-dispersive x-ray spectroscopy confirmed the incorporation of Ga on the PDA NP surface.
