摘要： The effects of Fe-3 or Fe-2 ions on the interaction of CS-Fe3O4@ZnS : Mn/ZnS Magnetic- Fluorescent Nanoparticles (MFNPs) with Bovine Serum Albumin (BSA) have been studied using UV visible and fluorescence spectroscopy. It was found that both the fluorescence intensity of CS-Fe3O4@ZnS : Mn/ZnS MFNPs and BSA became weakened when Fe-3 or Fe-2 concentrations reached their physiological levels. Meanwhile, the interaction of CS-Fe3O4@ZnS : Mn/ZnS MFNPs with BSA in the presence of Fe-3 or Fe-2 enhanced. There is synergic effect of CS-Fe3O4@ZnS : Mn/ZnS MFNPs and Fe-3 or Fe-2 on the damage of BSA. These results are important for understanding the influence of different biological environments on interaction between MFNPs and proteins.
