The present work investigate the green synthesis of zinc oxide nanoparticles (ZnO NPs) using Anacardium occidentale leaf extract by an eco-friendly method. ZnO NPs were synthesized by boiling the mixture of 10 ml of Anacardium occidentale leaf extract and 30 ml 0.1 M zinc nitrate (ZnNO3) at 60 °C for 3 h. The obtained nanoparticles were studied using spectroscopic and microscopic techniques such as Fourier transform-infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS) and ultraviolet-visible spectroscopy (UV–Vis).X-ray diffraction results showed the hexagonal structure of the ZnO NPs. TEM results confirmed the hexagonal NPs with average particle size of 33 nm. Further the prepared nanoparticles were studied for their cytotoxicity against human pancreatic cancer cells. The cytotoxicity results have confirmed that the fabricated ZnO NPs exhibited the concentration-dependent cytotoxicity against pancreatic cancer cell lines.

A facile, convenient, and green method for the synthesis of BAgNPs by using basalin is proposed in this work. The capping of the basalin on the surface of BAgNP was confirmed by the zeta potential and FTIR findings. Further, we have injected prepared BAgNPs into oxaliplatin-treated mice to alleviate neuropathic pain. The aluminum levels in the DRG were reduced by the chelating activity of BAgNPs. Moreover, behavioral analyses also manifested that the accumulation of aluminum on the DRG might be a reason for neuropathic hyperalgesia. These findings also recommended that the chelation of aluminum by AgNPs could provide an effective remedy to alleviate the symptoms of oxaliplatin-induced neuropathic pain in cancer patients.
