How nanomaterials act against bacterial structures? a narrative review focusing on nanoparticle molecular mechanisms.

Objective: In recent years, significant progress has been made in the field of nanotechnology for the treatment and prevention of biofilm formation and Multidrug-resistant bacteria (MDR). MDR bacteria challenges is hazardous when microorganisms induce the formation of biofilms, which amplify resistance to antibiotics and promote the development of multidrug-resistant conditions. The unique physicochemical properties of certain nanomaterials make nanotechnology a promising option for combating MDR infections. Several studies have introduced nanomaterials with different antibacterial mechanisms that can effectively destroy MDR bacteria and their biofilms. This study reviews the research results, focusing on the various nanoparticle mechanisms that target bacterial structures.
Method: To accomplish this study, we conducted investigations to gather articles and relevant studies from validated medical databases such as Scopus, PubMed, Google Scholar, and Web of Science. The selected publications from 2007 to 2023. In this review, we provide a brief overview of nanoparticles, their mechanisms, and how they function against the structure of bacteria. Furthermore, we discuss the recent advancements in using certain nanoparticles to combat infection-induced biofilms and complications caused by multidrug resistance.
Finding: Our findings demonstrate that various nanoparticles have the potential to effectively overcome bacterial infectious diseases by targeting biofilms and antibiotic-resistant strains. Additionally, the development of a new drug delivery approach based on nanosystems shows promise in overcoming antibiotic resistance and biofilms.
