biosynthesis of cu and cuo nanoparticles using aqueous leaves extract of sambucus nigra l.

In this research we are synthesized cuo nanoparticles (nps) using water extract of. also the totalphenolic content of sambucusnigra l. leaves water extract was measured by the folin-ciocalteu method.for confirmation the structure of synthesized bio-cuo-nps we are employed x-ray diffraction (xrd),ultraviolet-visible (uv–vis), fourier transform infrared (ftir) spectroscopies, scanning electronmicroscopy (sem), and transmission electron microscopy (tem) methods that indicated that synthesizedbio-cuo nps have crystalline face-centered cubic (fcc) cuo phase with spherical morphology and with sizeabout 14 nm. it should be mentioned that two different temperatures (100 and 400 ◦c) caused to cu andcuo nps respectively.
