“…Electromagnetic radiation will be reflected, absorbed, or emitted distinctly by different kinds of atomic particles. These characteristics allow spectroscopy to assess the nature of he sample 26,27 . UV-Vis absorbance plots of the synthesized Cu-NPs were recorded at various wavelengths between 200 and 1000nm at a scan rate of 200nm/min and are shown in Fig.…”

In the present study, Copper nanoparticles (Cu-NPs) are produced using Nerium Oleander leaf extract via a green process. The prepared samples were examined by powder‒X-ray diffraction (P-XRD), ultraviolet-visible (UV-Vis) spectroscopy; Fourier transforms infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM) and antibacterial screenings. According to XRD measurements, the Cu-NPs have a monoclinic form. According to UV-Vis study, the minimal absorbance between 250 and 1000 nm is due to by the formation of high-quality samples. The functional groups of Cu-NPs were verified by FT-IR spectroscopy. According to the FE-SEM analysis, the Cu-NPs are clusters of smaller cylindrical objects with good uniformity. The antibacterial results show that the samples are fairly effective against Escherichia coli and Salmonella typhi bacterium. The findings indicate that Cu-NPs can be used in the medical sector for surgical tools.
