Description :
Synthesis of green nanoparticles from biological material like plant extract, bacteria and fungi has become the matter of great interest due to its ecofriendliness and various applications in different fields. In the present study Terminalia arjuna (Roxb. ex DC) Wight and Arn. bark extract was used for the green synthesis of silver nanoparticles. The formation of silver nanoparticles was detected by spectrophotometrically by measuring the change in colour from reddish to dark brown after treatment with silver nitrate. The FESEM analysis revealed that the nanoparticles are spherical in shape ranges with 40-50 nm in size. These biologically synthesized nanoparticles showed the inhibition of Staphylococcus aureus and Pseudomonas aeruginosa bacteria. The zone of inhibition was significantly higher in Pseudomonas aeruginosa.
