Biological Synthesis of Silver Nanoparticles from Cochlospermum Religiosum and their Antibacterial Efficacy

The synthesis of ecofriendly nanoparticles is evergreen branch of nanoscience for biomedical application. In the present study biosynthesis of silver nanoparticles and its activity on bacterial pathogens were carried out. SNPs were rapidly synthesized using leaf extract of medicinal plant Cochlospermum religiosum and the formation of nanoparticles was observed within two minutes. The results recorded from UV-Vis spectrum and AFM analysis supports the biosynthesis and characterization of silver nanoparticles. The UV-Vis spectrum has the absorbance peak at 260 nm and the spherical shaped SNPs showed variation in size ranging from 40 to 100 nm. Further the synthesized SNPs showed effective inhibitory activity against pathogens Bacillus, E.coli, Pseudomonas, Klebsiella and Staphylcoccus. They are highly toxic to E.coli and Staphylococcus. Moderately toxic to Bacillus, Pseudomonas and Klebsiella.
