摘要：The study conducted to assess the characterization and antibacterial activity of gold nanoparticles ofFrangipani flower. The flower extract used to check antibacterial activity against Escherichia coli, Klebsiella, Serratia,Staph.epidermis, citrobacter and Proteus vulgariswere investigated.Gold nanoparticles using flower extract ofFrangipanias reducing agent. The complete reduction of gold chloride was observed after 48 h of reaction. Thecharacteristic color changes from pale yellow to dark brown during the formation of gold nanoparticles in the reactiondue to their specific properties “Surface Plasmon Resonance” was observed. The flower extracts acts as reducing aswell as encapsulate agent for the gold nanoparticles. The UV-Vis spectrophotometer, SEM, TEM and XRD was used tocharacterize the gold nanoparticles. The UV-visible spectrophotometer indicates a strong Plasmon resonance which islocated at 400 nm. The TEM, SEM images show that obtained samples have spherical morphology.
