Recent Advances in Enhancing Antibacterial Property by Nanoparticles

Abstract

Antibacterial activity is related to compounds that locally kill bacteria or slow down their growth, without being in general toxic to surrounding tissue. In this review, we mentioned the antibacterial property of different nanoparticles and their effects. Antibacterial agents are significant in the textile industry, medicine, food packaging, and water disinfection. In this study, we compared the antibacterial property of silver nanoparticles; silver coated gold nanoparticles, zinc oxide nanoparticle and iron nanoparticles. Silver nanoparticles can also be produced by biological methods because of the abundance of renewable, cost-effective and biodegradable materials while comparing the properties Au nanoparticles are biocompatible and relatively simple to prepare. The Zn nanoparticles did not require the protection layer to prevent the degradation of the performance of the antibacterial effect. The study of iron nanoparticles pattern with bacteria interface which affects the antibacterial property of IO NP. Ag NP-GT can be employed as a cytotoxic bactericidal agent, whereas Ag NP-OB (7.5 nm) as a biocompatible bactericidal agent. Au-Ag NPs immobilization on cellulose paper could be a valuable antibacterial technology for applications such as food packaging, clothing, wound dressings, and other personal care products. The chitosan coating of IONP result in an interface that enhances ROS production, hence the antimicrobial activity.
