Antibacterial activity of nanoparticles

Antimicrobial resistance (AMR) is predicted to soon become one of the most serious threats to human and animal health [1,2]. It can result in extended hospital stays, increased medical costs, and even death. Both the prevalence of AMR and the rise in biofilm associated infections are increasing the demand for new and reliable treatments for these infections. Nanotechnology offers a revolutionary new solution to this challenge. This analysis focuses on the most recent advancements in the field of antimicrobial, inorganic based nanomaterials, and their action against bacteria and bacterial biofilms. In this Special Issue, nanomaterials that prevent bacterial adhesion and nanomaterials that treat infections once they have developed are described. To combat infection, nanoparticles with inherent antibacterial activity and nanoparticles acting as nanovehicles are identified, with a focus on the design of carrier nanosystems with properties that target bacteria and biofilm
