Abstract
In the present studies, modified NiO nanoparticles and MnO2/NiO nanocomposites with guanidine were synthesized by anchoring method for carriers of anticancer drug “Caffeic acid phenethyl ester”. The prepared nanocomposites were characterized by using Scanning Electron Microscopy, Raman and Fourier transform infrared spectroscopy, X-ray diffraction, Vibrating sample magnetometer. The results from XRD indicated that the crystalline size of NiO nanoparticles and MnO2/NiO nanocomposites are 12 and 15nm, respectively. Saturation magnetization (Ms) for NiO NPs and MnO2/NiO nanocomposites was to be 0.60, and 0.68emu/g indicating that these are superparamagnetic and ferromagnetic properties in nature. The prepared nanocomposites were evaluated as catalyst for degradation of antibiotics in photocatalysis process. Particularly, the MnO2/NiO composite demonstrated the higher degradation rate (89.55%) of tetracycline antibiotic under UV light irradiation than the NiO (67.80%). Drug load on and release from nanopowders was investigated by using UV–Vis spectroscopy method. Time of drug loading was 100min and the drug release in 1–10h with 20–80% drug release were found, and then, it's applicable to in-vivo drug delivery. Therefore, the NiO nanoparticles and MnO2/NiO nanocomposites are promising for targeted Caffeic acid phenethyl ester anticancer drug delivery applications. The anticancer drug loaded on guanidine-NiO and guanidine-MnO2/NiO in high concentration has an antioxidant property.
