| 英文摘要 | Fe3O4 magnetic nanoparticles were prepared by co-precipitation and supported on the surface of aminopyridine-grafted multiwalled carbon nanotubes (MWCNT-AP), affording a superparamagnetic Fe3O4/MWCNT-AP composite with good dispersity. The Fe3O4/MWCNT-AP composites were characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), and hysteresis curve measurements. Transmission electron microscopy (TEM) experimental results suggest that the Fe3O4 nanoparticles are mainly adsorbed on the tips of the MWCNT-AP. UV-Vis absorption and fluorescence results demonstrate that horseradish peroxidase (HRP) can be physically adsorbed onto the surfaces of the Fe3O4/MWCNT-AP composite. Under acidic conditions (pH 4.0), the maximum reaction rate (v(max)) value of the HRP increases 3-fold after interaction with Fe3O4/MWCNT-AP. |
