Gold-, silver- and magnesium-doped zinc oxide nanoparticles prevents the formation of and eradicates bacterial biofilms - supplementary tables
Aim: This work aimed to synthesize magnesium-doped zinc oxide, silver and gold nanoparticles (Nps) and
to evaluate their potential to prevent and eradicate Escherichia coli, Proteus mirabilis, Staphylococcus
aureus, Acinetobacter baumannii and Pseudomonas aeruginosa biofilms. Materials & methods: The Nps
were synthesized by precipitation and metallic reduction techniques. Physicochemical and biological
characterization of Nps was performed. Results: All the Nps tested were able to inhibit the formation of E.
coli, P. mirabilis, S. aureus and A. baumannii biofilms. The effects on the eradication of preformed biofilms
were variable, although all the Nps tested were able to eradicate A. baumannii biofilms. Conclusion: The
observed effects make the Nps suitable for coating surfaces and/or antibiotic carriers with medical interest.
