The catalytic activity with size effect
The catalytic activity: one of Fe3O4 MNPs with diameter at 300nm≈one HRP molecule.
Catalytic activity with surface modification
Kcat (M-1S-1) 3.37 ×109 3.72×108
Kcat (M-1S-1)
9.68×109 3.24×108
[E] is the enzyme (or MNP) concentration, Km is the Michaelis constant, Vmax is the maximal reaction velocity and Kcat is the catalytic constant, where Kcat=Vmax/[E].
