MnO2 nanozyme-doped diatom microbubbler (DM) antibacterial effects in peri-implantitis. A MnO2 NZ-doped DM was recently developed. B and C By simulating the activity of CAT in H2O2 solution, DM is capable of producing oxygen and moving with the ejection of oxygen microbubbles, thereby creating a mechanical self-cleaning effect. CHX eradicated S. mutans but was incapable of eliminating the majority of biofilms on brackets [130]
