Annona reticulata leaves-assisted synthesis of zinc oxide nanoparticles and assessment of cytotoxicity and photocatalytic impact

초록

The objective of this study is to examine the novel usage of the aqueous leaf extract of Annona reticulata (AR) to produce zinc oxide nanoparticles (AR-ZnONPs) by reducing zinc nitrate. Fourier-transform infrared (FT-IR) spectroscopy analysis revealed that phytochemical compounds in AR leaf extract was responsible for capping and effective stabilization of AR-ZnONPs. The energy-dispersive X-ray (EDX) spectra showed the existence of a zinc peak at 1 keV. In addition, the arrangement of a face-centered cubic crystalline construction was also confirmed by X-ray diffraction (XRD) analysis. The biologically produced AR-ZnONPs have a potential cytotoxicity effect against human lung cancer (A549) cells. Furthermore, AR-ZnONPs exhibited tremendously degradation efficiency for the methylene blue (MB) almost 93.45% removal in 70 min sunlight irradiation.
