Biosynthesis and Cytotoxic Properties of Ag, Au, and Bimetallic Nanoparticles Synthesized Using Lithospermum erythrorhizon Callus Culture Extract

Abstract: The present study reports a green chemistry approach for the rapid and easy biological synthesis of silver (Ag), gold (Au), and bimetallic Ag/Au nanoparticles using the callus extract of Lithospermum erythrorhizon as a reducing and capping agent. The biosynthesized nanoparticles were characterized with ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD) analysis, and transmission electron microscopy (TEM). Our results showed the formation of crystalline metal nanostructures of both spherical and… Show more

“…This result corroborates with the previously published nanoparticle synthesis results [24]. A change in the SPR of Bbf-AgNPs prepared with the Bbf extract was observed compared to that of the Fbf-AgNPs prepared with the Fbf extract might be due to the blue shift due to the decrease in the refractive index of the dielectric environment surrounding the synthesized nanoparticles [25,26]. The basic morphology, characteristics, and elemental composition of both the Fbf-AgNPs and Bbf-AgNPs were estimated by SEM and EDX assessment.…”

“…In a study by Lomelí-Marroquín et al they showed that the biosynthesized Ag-Au nanoparticles could inhibit the cell proliferation of human melanoma cells (Lomelí-Marroquín et al 2019 ). In addition, Shkryl et al showed that the green synthesized Ag-Au nanoparticles exhibited cytotoxicity against mouse neuroblastoma and embryonic fibroblast cells, but the anticancer activity was not assessed (Shkryl et al 2021 ). Accordingly, we intended to study the anticancer activity and cytotoxicity of our green synthesized Au@AgNPs on hepatocellular carcinoma cell lines.…”
