Do Iron Oxide Nanoparticles Have Significant Antibacterial Properties?

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Microbiology

Background:

• Antibiotic resistance is a growing global health threat.
• Metal oxide nanoparticles, particularly iron oxide nanoparticles (IONPs), are being explored for antimicrobial applications.
• IONPs have diverse biomedical applications and their antimicrobial potential is under investigation.

Purpose of the Study:

• To review the antimicrobial properties of IONPs.
• To explore the range of susceptible bacteria and fungi.
• To discuss the mechanisms of antibacterial action and biocompatibility of IONPs.

Main Methods:

• Literature review of studies on IONPs' antimicrobial activity.
• Analysis of data on susceptible bacterial and fungal strains.
• Evaluation of research on IONP synthesis methods and their impact on efficacy.
• Assessment of biocompatibility studies with eukaryotic cells and tissues.

Main Results:

• IONPs demonstrate antimicrobial effects against Gram-negative and Gram-positive bacteria and fungi.
• Studies indicate low toxicity of IONPs to eukaryotic cells.
• The antibacterial efficacy of IONPs can depend on their synthesis method.

Conclusions:

• IONPs show potential as next-generation antimicrobial agents due to their combined antimicrobial action and high biocompatibility.
• Further research is warranted to optimize IONP synthesis for enhanced therapeutic applications.
• IONPs represent a promising strategy to combat antibiotic resistance.
