| Abstract: | The magnetic nanoparticle Fe3O4 and multi-walled carbon nanotubes （MWNTs） were solubilized in aqueous solution of a biopolymer chitosan （CHIT）. A new biosensor was made by the intermixture decorated on the surface of the glassy carbon electrode to fix the glucose oxidase（GOD） with glutaraldehyde. InPBS（pH=6.8）, the linear dependence current of the biosensor was in the range of 1.0×10^-5-2.3×10^-2 mol/L, the response lime was 5.3 s. |
