Potential of Biosynthesized Heavy Metal Nanoparticles as Antibacterial Agents in Water Treatment Applications: A Review

The need to explore new, sustainable water treatment methods is defined by an increasing prevalence of pathogenic bacteria in rivers. Biosynthesized heavy metal nanoparticles, or ''BHMNs'', are ''an'' examples of what could be termed environmentally heavy technology. The antibacterial efficiency of ''BHMNs'' in water treatment applications is systematically studied in this article. We surveyed many biological sources used to preparation ''BHMNs'' and gave reasons why these methods should be regarded as alternatives to traditional ones. The review also explores the different mechanisms by which ''BHMNs'' exercise their antibacterial effects including membrane rupture, DNA breakdown, and the production of reactive oxygen species. Another topic dealt with in the review is an appraisal, based on recent studies, of the efficiency of ''BHMNs'' as an antidote to a range of aquatic maladies. In addition, the review discusses potential disadvantages of widespread use of ''BHMNs'' in water treatment, including output increase and stability over time as well as environmental impact. based on recent studies We point out that the increased application of BHNs in water treatment is expected to yield a greater antimicrobial effect by showing the potential of BHMNs as a sanitary alternative to traditional techniques. This review aspires to further contribute developments in sustainable.
