To explore the preparation and characters of a novel nanosized magnetic liposome that contained PEI-As2O3/Mn0.5Zn0.5Fe2O4 (PEI- As2O3/MZF) complex. Experimental results suggest that PEI-As2O3/MZF magnetic nanoliposome is a kind of appropriate material which has multiple effects for tumor thermotherapy, gene therapy and chemotherapy.
In somatic gene therapy, new concepts for the transfer of DNA into specific cell nucler are of interest. In this study, the feasibility of using magnetic nanoparticles with chemotherapeutant (PEI-As2O3/ Mn0.5Zn0.5Fe2O4) as gene vector is evaluated. Mn0.5Zn0.5Fe2O4 magnetic nanoparticles(MZF-NPs), obtained through co-precipitation method, were firstly combined with As2O3 to prepare As2O3/Mn0.5Zn0.5...
A new dinuclear complex, [Ag(L)(CH 3 CN)] 2 (ClO 4 ) 2 2H 2 O(L=2,3-di-2-pyridylquinoxaline), was prepared and characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction analyses. The interaction of the complex with calf thymus DNA(CT-DNA) was investigated by absorption, fluorescence spectroscopies, and viscosity measurement....
