Silver nanoparticles (AgNPs) have emerged as promising nano-antimicrobials due to their broad-spectrum bactericidal activity. In this paper, we have reported the synthesis of silver nanoparticles (AgNPs) with desired size and high purity using tartaric acid and sodium dodecyl sulphate (SDS). In the synthetic reaction, tartartic acid acts a reducing agent and sodium dodecyl sulphate (SDS) which acts a capping agent and it controls the growth of the particles in the range of nanoparticles. The synthesized AgNPs were characterized by modern method and tools such as UV-Vis. Spectroscopy, dynamic light scattering (DLS), scanning electron microscope (SEM), Energy-dispersive X-ray spectroscopy (EDAX) and transmission electron microscope (TEM). These AgNPs have been used to investigate the anti-bacterial activity study and this study describes that AgNPs gives very good results. IC50 (half-maximal inhibitory concentration) values were found 61.9 μg/ml and 96.7 μg/ml against Staphylococcus aureus and Escherichia coli bacteria respectively for which silver nanoparticles shows very much potent efficacy against both Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative) bacteria, which conclude that these silver nanoparticles are very effective towards broad spectrum antibacterial applications.
