عنوان انگلیسی Mg-doped NiO Nanoparticles Decorated Multi-Walled Carbon Nanotube (MWCNT) Nanocomposite and their Biological Activities
چکیده انگلیسی مقاله Here we report a novel nanocomposite composed from Mg-doped NiO and Mg- dopedMWCNTs using a facile sol-gel method. The synthesized Mg-doped NiO and Mg- dopedMWCNTs nanocomposite w::as char::acterization by XRD diffraction Analysis (XRD), Energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), Filed Emission scanning electron microscopy (FESEM), and UV-Vis spectrophotometer. The X- Ray analysis revealed that the formation of nanocomposites, which has a cubic phase and a high crystalline nature. The FE-SEM images confirmed the success of decoration the Mg- doped NiO on the surface of the treated MWCNTs through the emergence of spherical shapes over the cylindrical tubes. Conversely, optical measurements reveal that the energy gap value for the Mg- NiO and the Mg/NiO-MWCNTs nanocomposite are 3.28 eV and 2.82 eV, respectively. This indicates decreasing the zone between conduction band and valence band. Moreover, it found that Mg-doped NiOMWCNTs nanocomposite showed high removal efficiency towards the lead element compared with the Mg-doped NiO. Also, MTT test was employed to study antitumor activity against MCF-7 and WRL68 cells. Our results showed that the Mg doped NiO-MWCNTs had cell viability of 66.7% and 71.9 % against MCF-7 and WRL68, respectively. In state of Mg- doped NiO sample was display cell viability of 70.2% and 71.9 % against MCF-7 and WRL68, respectively.
