Metal/metal oxide nanocomposites for bactericidal effect: A review

Area of Science:

• Materials Science
• Microbiology
• Nanotechnology

Background:

• Multidrug-resistant microbes pose a significant global health threat, leading to increased mortality and morbidity.
• Existing treatments are often ineffective, necessitating novel infection control strategies.
• Nanoparticles offer a promising avenue for developing advanced antimicrobial agents.

Purpose of the Study:

• To review the antibacterial activity of metal and metal oxide nanocomposites.
• To explore the novel mechanisms by which these nanocomposites combat microbial infections.
• To highlight the potential of nanocomposites in addressing the challenge of multidrug resistance.

Main Methods:

• Literature review focusing on metal and metal oxide nanocomposites.
• Analysis of research on their synthesis and characterization.
• Examination of studies detailing their antibacterial mechanisms.

Main Results:
