Nanoparticles are one of the most important technologies of today and the future. This groundbreaking technology is considered a very significant domain among all the fields of science due to its tangible capacity in improving products, treating diseases, serving mankind in all spheres of life, and realizing future scientific revolutions in the fields of physics, chemistry, biology, engineering, and other sciences.  Therefore, it is truly necessary to take advantage of the distinct properties of nanomaterials. Hence, synthesized nanoparticles have been shown to be enjoying anti-proliferating antioxidant, anti-migration, antioagulant and anti-cancer antipathogenic characteristics in the laboratory.  Accordingly, this study came to prominence in this field. The biochemical equipment used in nanoparticle bacterial biosynthesis was subsequently proven. Many of these biochemical types of equipment have been used as part of a cellular detoxification resistance mechanism that involves altering inorganic ions solubility by reducing and/or precipitating soluble toxic to insoluble non-toxic nanostructures. Microorganisms, such as bacteria, are used as an environmentally responsible strategy, and an alternative in the method of chemical agents when nanoparticles are synthesized. Extracellular as well as intracellular biocatalytic (including possible excretion) synthesis involves mainly oxidreductase enzymes like NADH dependent reductase nitrate NADPH, NADPH sulphite reductase alfa (NADPH dependent on sulfite reductase) and cells.

Theg useg of microorganisms like bacterial in the synthesis of nanoparticles emerges as an eco-friendly approach and an alternative to the chemicals method. In the presentg study, reported the biosynthesis of silver nanoparticles (AgNPs) using the Streptococcus pyogenes. Silver nanoparticles were synthesized through the reduction ofg aqueous Ag + ion using the bacterial culture supernatants at room temperature. Synthesis of AgNPs was initially observed by color change from yellow to brown which was confirmed by UV-visible spectroscopy The silver nanoparticles were further characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopic (SEM) analyses and X_ ray diffraction (XRD). The synthesized nanoparticles were found to be spherical in shape with ag size in the range of 20-100nM. The synthesized AgNPs were found to have antibacterial activity against two tested pathogenic bacteria (Gram negative bacteriag E.coli and Gram positive bacteriag S. aureus.
