(a) Relation of CuO NPs concentration and Absorbance (Moris Nigra), (b): Effect on the synthesis of CuO NPs due to gradual increase in the M. nigra leaf extract concentration.
(a) Relation of CuO NPs concentration and Absorbance Melia azedarach (dharaik), (b): Effect on the synthesis of CuO NPs due to the gradual increase in concentration of Melia azedarach (dharaik) leaf extract.
A= pale blue (0.01M CuSO4.5H2O); B= greenish brown (aqueous leaf extract of Morus nigra); C= dark brown (addition of leaf extract into CuSO4.5H2O).
Colour change from pale blue to yellowish green and finally dark brown (left to right) for Melia azedarach.
An increase in absorbance is observed with Morus nigra (a) and Melia azedarach (b) increased leaf extract concentration i.e. 5% to 25%.
FTIR spectrum of CuO nanoparticles synthesized from M. nigra (a) and Melia azedarach (b) leaves extract.
XRD plot of CuO NPs synthesized from M. nigra (a) and Melia azedarach (b) leaf extract.
Showing the antibacterial results of CuO NPS synthesized from Morus nigra (M.n) and Melia azedarach (M.a) leaf extracts against a) Eschericia coli b) Clostridium tetani (M.n) c) Clostridium tetani (M.a) d) P. mirabilis e) Salmonella (M.n) f) Salmonella (M.a).
