Metal-based nanoparticles: an alternative treatment for biofilm infection in hard-to-heal wounds

J Wound Care. 2024 Apr 2;33(Sup4a):xcix-cx. doi: 10.12968/jowc.2024.33.Sup4a.xcix.

Abstract

Metal-based nanoparticles (MNPs) are promoted as effective compounds in the treatment of bacterial infections and as possible alternatives to antibiotics. These MNPs are known to affect a broad spectrum of microorganisms using a multitude of strategies, including the induction of reactive oxygen species and interaction with the inner structures of the bacterial cells. The aim of this review was to summarise the latest studies about the effect of metal-based nanoparticles on pathogenic bacterial biofilm formed in wounds, using the examples of Gram-positive bacterium Staphylococcus aureus and Gram-negative bacterium Pseudomonas aeruginosa, as well as provide an overview of possible clinical applications.

Keywords: Pseudomonas aeruginosa; Staphylococcus aureus; bacterial infections; biofilms; chronic wound; hard-to-heal; microorganisms; nanoparticles; wound; wound care; wound dressing; wound healing.
