Biosynthesis of ZnONP Using <i>Chamaecostus cuspidatus</i> and Their Evolution of Anticancer Property in MCF-7 and A549 Cell Lines

Abstract

The ZnO nanoparticle synthesis using the leaf part of Chamaecostus cuspidatus was characterized using UV–Vis spectrophotometry, IR, XRD, DLS, FESEM, EDX, TEM, AFM and XPS. The MTT assay was used to examine the cytotoxicity activity against lung epithelial and breast cell lines, and the IC50 value was determined. The presence of ZnO nanoparticles, which range in size from 200 to 800 nm, was confirmed by the absorption peak at 350 nm. The median particle size was 145.1 nm, and the ζ -the potential was −19.45 mV, showing that ZnONP is stable. Zinc, carbon, and oxygen contribute to the elemental composition of ZnONP, as determined by EDX analysis. MTT assay was used to investigate in vitro cytotoxicity in MCF-7 and A549 cell lines. The cytotoxicity activity IC50 value was determined to be 30 μg/mL for the A549 cell line and 37 μg/mL for the MCF-7 cell line.
