Prussian blue modified iron oxide magnetic nanoparticles and their high peroxidase-like activity
Prussian blue iron oxide magnetic nanoparticles high peroxidase-like activity
2010/7/16
Prussian blue (PB) modified g-Fe2O3 magnetic nanoparticles (MNPs) featuring varying PB proportions were synthesized and characterized by TEM, FTIR, UV-vis, EDS, XRD and XPS. The magnetic properties an...
The quasi-one-dimensional assembly of horseradish peroxidase molecules in presence of the alternating magnetic field
Electromagnetic field Protein molecules Assembly
2010/7/16
Here we reported the assembly of horseradish peroxidase molecules mediated by the alternating
magnetic field. The field can make quasi-one-dimensional assembly conformations. We proved the phenomenon...
