Nanoparticles as Antimicrobial Agents: Their Toxicity and Mechanisms of Action

Bacterial strains that are resistant to current antibiotics have become serious public health problems that increase the need to develop new bactericidal materials. Therefore, nanoparticles have gained importance in the field of chemotherapy. This review is focused on the unique properties of nanoparticles and their mechanism of action as antibacterial agents. The activities of nanoparticles on drug-resistant bacteria and risks of using them as antibacterial agents also have been documented.
