Here we successfully demonstrated Papaver somniferum L. mediated green synthesis of lead oxide (PbO) and iron oxide (Fe2O3) nanoparticles. Characterization of nanoparticles involved techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and energy dispersive X-ray (EDX) associated with scanning electron microscopy (SEM). XRD analysis confirmed the phase identification and crystalline nature. FTIR analysis confirmed the capping of nanoparticles by plants' phytochemicals. SEM revealed morphological features of PbO and Fe2O3 with size of nanoparticles being 23 ± 11 nm and 38 ± 13 nm, respectively. The elemental composition of the nanoparticles was confirmed by EDX. Both bacterial and fungal isolates showed susceptibility towards PbO and Fe2O3 NPs. Both the NPs also showed considerable total antioxidant potential, free radical scavenging potential and reducing power. Insignificant level of α-amylase for both NPs was observed. Fe2O3 NPs showed superior biocompatibility with human RBCs as compared to PbO whereas PbO showed more potent anti-cance...
