Cansjera rheedii J. F. Gmel. a medicinal plant-mediated synthesis of silver nanoparticles and their antibacterial activity

The laboratory experiments were conducted to synthesis silver nanoparticles using the leaf extract of Cansjera rheedii J. F. Gmel. The characteristic Plasmon resonance at 430 nm in UV-Vis spectrophotometer confirmed the formation Silver nanoparticles. The FTIR data reveals the possible functional groups of biomolecules involved in bioreduction and capping for efficient stabilization of silver nanoparticles. HRSEM studies revealed that the nanoparticles are spherical in shape and size ranges between 30 and 50 nm. These silver nanoparticles were evaluated for their antibacterial efficacy against the bacteria Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. The Silver nanoparticles inhibited the growth of Pseudomonas aeruginosa and staphylococcus aureus but no inhibition was observed in case of Escherichia coli.
