 was used to synthesize eco-friendly gold nanoparticles, AUNPs, which were characterized by X-ray diffraction, XRD, transmission electron microscopy, TEM, energy dispersive spectroscopy, EDS, failure transform infrared spectroscopy, FTIR, and scanning electron microscopy, SEM. The AUNPs showed excellent anti-cancer activity against HEPG2 and A549 cell lines. This article was authored by S Rajascoma.
