Abstract

The unique property of the silver nanoparticles having the antimicrobial activity plays an important role in present nanotechnology. The environmentally non-toxic and eco-friendly silver nanoparticles production from the plant extracts creates the major research interest in the field of nanobiotechnology. The present research study was the biogenic synthesis of the silver nanoparticles with a precise stability from the bark extract of Syzygium cumini, which is a medicinal plant available in the tropical forests, and it has best anti-diabetic property. In this study we had done the characterization through the UV-Visible spectroscopy, Atomic force microscopy, Dynamic light scattering, and Scanning electron microscopy. From all above characterization techniques the synthesized nanoparticles shows average size from 40 nm to 80 nm and these nanoparticles are polydispersive and uniform in distribution. The synthesized nanoparticle shows antibacterial property and has a better zone of inhibition with the different pathogenic bacteria species such as Escherichia coli, staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus licheniformis 9555. The zone of inhibition was characterized by the well plate method at different concentrations of 2, 5, 10, 15, 25, 50, 75 and 100 μL. Nanoparticles had a wide variety of application in medicine, electronics, chemistry and other related sciences. These nanoparticles are used in electronics, household hospitals appliances, cleaning agents, odor textiles, water drainage systems, food packaging materials and supplements, etc.
