A strategy for the treatment of non-small-cell lung cancer by Ag nanoparticles

Abstract

This work describes an eco-friendly approach for the green formulation of Ag nanoparticles by Allium ampeloprasum extract, without using any toxic reducing and capping agents. The morphology, structure, and physicochemical properties were characterized by several analytical techniques such as fourier transformed infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Ultraviolet–visible spectroscopy (UV–Vis). The nanoparticles were explored biologically in the anticancer assays. Exposure of the nanoparticles samples to non-small-cell lung cancer cells resulted in cell death, which was mostly due to necrosis but slightly due to late apoptosis. The viability of malignant cell lines reduced dose-dependently in the presence of nanoparticles. The IC50 of nanoparticles were 301, 266, 255, and 250 µg/mL against EKVX, HOP-62, A549 and NCI-H460 cancer cell lines, respectively. The green-synthesized nanoparticles induced cell death, suggesting anticancer prospects that may offer new insight into the development of an anticancer nanomedicine.
