The kinetic constants of Tb₄O₇ NPs

	[E] (M)	Km (M)	Vmax (M/s)	Kcat (s−1)	Kcat/Km (M−1 S−1)
Tb4O7 NPs	7.04 × 10−10	1.24 × 10−4	4.31 × 10−8	1.61 × 10−4	1.30

[E] is the concentration of Tb₄O₇ NPs. The particle number of Tb₄O₇ NPs is calculated using the density and diameter of Tb₄O₇ NPs. Dividing the particle number by the Avogadro constant is the molar concentration of Tb₄O₇ NPs
