Abstract:
In recent times, nanoparticles of copper oxide (CuO-NPs) are being considered one of the celebrated and resourceful nanoparticles with their physicochemical characteristics and their vast application in nanoscience. An environmentally modest methodology was embraced in the preparation of aqueous neem (Azadirachtin indica) leaves stabilized CuO-NPs. They were characterized by FT-IR, TEM-ImageJ software that reflects the heterogeneous particles distribution with the setting conditions (image J) of (81.4222) distance in pixels, known distance of 500 pixels, the aspect ratio of 1.0, and unit scale of (0.1628 pixels/nm). Ten nanoparticles were identified and calculated for the mean area, standard deviation, and dispersity indices with the actual mean area of 1245.755 ± 9.4263 nm2 and mean dispersity index of 1387.78 ± 319.98 ( >1; polydispersity). Technically, a zeta potential of -17.8 mV justifies the stability and the dispersion of CuO-NPs in the system. Hence, these outcomes could enhance the characteristics studies, manipulations, and applications of CuO-NPs in the nearest future.
