Peroxidase activity of MIMO@LA@AuNPs: (a) initial rate dependence towards ABTS concentration; and (b) initial rate dependence towards H₂O₂ concentration. Reaction conditions were: 50.0 mM phosphate buffer pH 6.5 50% TFE (v/v); MIMO@LA@AuNPs enzyme concentration 3.5 × 10⁻⁷ M. For the experiments performed at variable ABTS (a), the H₂O₂ concentration was 30.0 mM. For the experiments performed at variable H₂O₂ (b), the ABTS concentration was fixed at 5.0 mM.
