Facile synthesis of ultrasmall magnesium peroxide nanoparticles for antibacterial applications

摘要

As a precursor of H2O2, MgO2 attracts great attention in antibacterial applications. Ultrasmall MgO2 nanoparticles possess large surface area and high reactivity, presenting a potential to further improve the antibacterial efficiency. However, the synthesis of uniform ultrasmall MgO2 nanoparticles is still a great challenge. Here, MgO2 nanoparticles with an average diameter of 5 nm have been facily synthesized. The ultrasmall nanoparticles demonstrate superior bacteriostatic efficacy against E. coli and S. aureus due to the ablity to burst release reactive oxygen species.
