Orchid-flower-shaped ZnO nanomaterials were successfully synthesized via green synthesis and an eco-friendly approach using an aqueous extract of Lycium chinense fruit as a reducing and capping agent. The synthesized Lycium chinense orchid-flower-shaped ZnO (LC-ZnO/OF) nanoparticles (NPs) were characterized using different analytical methods through X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), photoelectron spectroscopy (XPS), and photoluminescence (PL). The FE-TEM analysis revealed the orchid flower shape of the nanoparticles, and the elemental composition was confirmed via XPS analysis. The photocatalytic activity of the nanoparticles was determined by the degrading cationic dye methylene blue (MB) and the anionic dye Eosin Y (EY) under visible light irradiation at (400 w) within 180 min time, where it showed a significant ability to degrade both cationic and anionic dye by almost 50%. The LC-ZnO/OF photocatalyst was also used to check the toxicity level in human cancer cells, where it exhibited remarkable cytotoxicity to the human lung cancer (A549 cell line) and human gastric adenocarcinoma hyperdiploid (AGS cell line). The present investigation suggests that LC-ZnO/OF has the potential photocatalytic ability to degrade toxic dye as well as have anti-cancer effects. These preliminary results suggest that LC-ZnO/OF could have a significant impact on the environmental and biomedical fields. |
