Summary

This narrative review synthesises current evidence on silver nanoparticles (AgNPs) as antimicrobial agents, with particular focus on their mechanisms of action against multidrug-resistant (MDR) bacteria. The paper likely covers key challenges including cytotoxicity, environmental persistence, and bacterial resistance development, alongside innovations in nanoparticle synthesis and functionalisation. It appears intended to provide a comprehensive overview of the state of the field for researchers and clinicians working on alternative antimicrobial strategies.

UK applicability

Antimicrobial resistance is a significant public health priority in the UK, and findings on AgNPs as alternative antimicrobial agents are relevant to UK research, healthcare, and regulatory contexts, including MHRA oversight of nanomaterial-based therapeutics. However, as an international review, specific translation to UK clinical practice would require further regulatory and safety evaluation.

Key measures

Antimicrobial mechanisms; minimum inhibitory concentrations; resistance profiles of multidrug-resistant bacteria; nanoparticle synthesis methods and physicochemical properties

Outcomes reported

The review likely examines the antimicrobial mechanisms of silver nanoparticles, their efficacy against multidrug-resistant bacteria, and current challenges and innovations in their development and application.
