A hollow core-satellite ZIF-8/PDA/AgNPs was established and studied as an antibacterial agent. Polydopamine (PDA) was coated on ZIF-8 surface to form a hollow structure because ZIF-8 core was etched by the chelation of PDA and Zn2+. Then AgNPs were homogeneously decorated on the surface of ZIF-8/PDA by in situreduction of Ag+to avoid their aggregation. ZIF-8/PDA/AgNPs have good antibacterial activity, and they can totally inhibit bacterial growth at the concentration of 16 µg mL−1.A hollow core-satellite ZIF-8/PDA/AgNPs composite was established with PDA shell to etch ZIF-8 core and AgNPs decoration on the surface. The composite had good antibacterial activity to inhibit bacterial growth by interaction with bacterial membrane.
