A REVIEW ON SYNTHESIS AND THEIR ANTIBACTERIAL ACTIVITY OF SILVER AND SELENIUM NANOPARTICLES AGAINST BIOFILM FORMING STAPHYLOCOCCUS AUREUS
Poonam Verma*
ABSTRACT Antibacterial agents are very important in the textile industry, water disinfection, medicine, and food packaging. Organic compounds used for disinfection have some disadvantages, including toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide nanoparticles (NPs) is increasing. This review focuses on the Preparation and their potential with good antimicrobial activity of Ag-NPs and Se-NPs against biofilm forming S. aureus. Such improved antibacterial agents locally destroy bacteria, without being toxic to the surrounding tissue. We also provide an overview of opportunities and risks of using NPs as antibacterial agents. In particular, we discuss the role of Ag-NPs and Se-NPs materials. Several manufactured nanoparticlesparticles with one dimension less than 100 nm are increasingly used in consumer products. At nano size range, the properties of materials differ substantially from bulk materials of the same composition, mostly due to the increased specific surface area and reactivity, which may lead to increased bioavailability and toxicity. Thus, for the assessment of sustainability of nanotechnologies, methods of manufacturing Nanoparticles, properties have to be studied. The formation of nanoparticle and physiochemical parameters such as pH, monomer concentration, ionic strength as well as surface charge, particle size and molecular weight are important for drug delivery. Further, these nanoparticles have the capability to reverse multidrug resistance a major problem in chemotherapy. Well-established therapies commonly employed in cancer treatment include surgery, Chemotherapy, immunotherapy, and radiotherapy. The silver nanoparticles might be involved in neutralizing these adhesive substances, thus preventing biofilm formation. Selenium is also one of essential trace elements in the human body and has great importance in nourishment and medicine. Medical diagnostic field also developed to use the selenium nanoparticles and also studies on the increase efficiency of glutathione peroxidase and thioredosin reductase.
