Enhanced multifunctionality of CuO nanoparticles synthesized using aqueous leaf extract of Vernonia amygdalina plant

We report the synthesis of medicinal plant, Vernonia amygdalina Del. mediated green copper oxide nanoparticles (VeA-CuO NPs). The presence two absorbance maxima, λmax 1 and 2 at 436 nm 452 nm, respectively confirms a mixture biomolecules surface amalgamated CuO NPs with different morphological features. FT-IR spectra plant leaf extract VeA-CuO confirmed efficient role as capping stabilising agents. XRD patterns approved high crystallinity CuO. purity was corroborated by SEM-EDAX analysis. average particle size found to be 19.68 nm. In addition, combined TEM, HRTEM SAED analysis substantiated d-spacing value 0.2854 which conformed (1 1). antibacterial assay revealed that were synergistic in their influence versus bacterial strains, S. aureus, E. coli, P. aeruginosa, aerogenes. uppermost zone inhibition 15 mm observed for bioactive compounds capped around served effective disrupting cell wall strains. degradation efficiencies Indigo carmine (IC) Malachite (MG) dyes 95% 91%, respectively. lowest half-life recorded 16.55 min MG dye. better electrode stability CV EIS studies, multi-functional nature NPs, these exhibited multifunctional applications.
