Biogenic synthesis of Copper nanoparticles using the Delonix elata flower extract was carried out as various literature resources revealed the importance of Delonix elata flower and Copper nanoparticles. Copper nanoparticles were prepared by adopting standard procedure. The formations of Copper nanoparticles from the Delonix elata flower extracts were identified first by observing the colour changes. The Delonix elata flower extract colour gets changed during the formation of Copper nanoparticles from dark brown to light green colour. Copper nanoparticles formed were characterized by UV, FT-IR, XRD and SEM. UV absorbance at 328nm for Copper nanoparticles. The IR spectrum of copper nanoparticles showed Cu –O stretching at 403cm-1 and proved by the diminished intensity of bonded OH(3200-3400cm-1) of the IR spectra of Delonix elata flower extract. XRD & SEM analysis of copper nanoparticles indicated that they exist in amorphous in nature and with size range 20μm.
