Boron-reinforced zinc oxide nanoparticles produced by the hydrothermal method: A novel antimicrobial agent

In this study, boron-doped zinc oxide (B/ZnO) nanoparticles (NPs) were synthesized using the hydrothermal method. Different boron (B) concentrations (5%, 10%, 15%, and 20% by weight) were chosen to produce B/ZnO nanocomposites. The antibacterial and anti-biofilm properties of the characterized B/ZnO NPs were also investigated against some pathogenic microorganisms. The NPs had a significant inhibitory effect on the microorganisms. The anti-biofilm analysis revealed that these NPs inhibited the biofilm formed by both Escherichia coli and Pseudomonas aeruginosa bacteria. Significantly, 20% B-doped ZnO nanocomposites are the most effective nanocomposite and can be used as an alternative to antibiotics for antimicrobial therapy.
