Biological synthesis, characterization of three metal-based nanoparticles and their anticancer activities against hepatocellular carcinoma HepG2 cells.

Treatment of liver cancer has always been a challenge for clinicians and development of appropriate drug against hepatocellular carcinoma is the major focus for researchers working in the field. The synthesis of metal-based nanoparticles (NPs) by green method for pharmacological uses has attained considerable attention recently. In current study three different NPs (AgO2, CeO2, CuO2) were synthesized by using Trianthima portulacastrum and Chinopodium quinoa leaf extracts. These biogenic NPs were analyzed by High-tech. approaches including Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray (EDX) spectroscope, SEM-EDS spot analysis, elemental mapping and X-ray diffraction (XRD). The anticancer potential of these nanoparticles was estimated using MTT assay, against hepatic cancer cell line (HepG2). SEM secondary electron images presented the nano size of prepared particles in agglomerated form with few porous forms. Average size of Ag-, Ce-, and CuNPs was observed 19-24 nm, 8-12 nm, 13-15 nm respectively. Elemental mapping and EDS-spot analysis ratifies the formation of AgNPs, CeNPs, and CuNPs. These NPs have shown good anticancer activity at different concentrations against HepG2 cell line. Further studies are however needed to identify the molecular mechanisms of these anticancer activities.
