(A) Time-dependent absorbance changes of oxidation of TMB in the presence of H₂O₂. Effects of TMB concentration (B), H₂O₂concentration (C), Ags-APMSNs concentration (D), pH (E), and temperature (F) on catalytic activity of the Ags-APMSNs. Reaction conditions: (A) 0.4 mM TMB, 100 mM H₂O₂, and 0.05 nM APMSNs; (B) 100 mM H₂O₂, 0.05 nM APMSNs and 10 min; (C) 0.4 mM TMB, 0.05 nM APMSNs and 10 min; (D) 0.4 mM TMB, 100 mM H₂O₂ and 10 min; (E) 0.4 mM TMB, 100 mM H₂O₂, 0.05 nM APMSNs and 10 min at different pH; (F) 0.4 mM TMB, 100 mM H₂O₂, 0.05 nM APMSNs and 10 min at different temperatures.
