%X We prepared Fe3O4 magnetic nanoparticles (MNPs) with the size of 10 nm by chemical coprecipitation.The effects of six aqueous-organic solvents,including tetrahydrofuran,dioxane,acetone,N,N-Dimethylformamide,methylalcohol,and Dimethyl Sulfoxide,on peroxidase mimetic activity of Fe3O4 MNPs were studied and compared with that of horseradish peroxidase (HRP).The relative activity of Fe3O4 MNPs droped sharply as the elevation of organic solvent concentration increased from 30% to 75% (V/V).In 15% organic solutio...
