6374 509 AuNPs@C.CNF POD TMB 4.0 RT 0.149 mM 10.68 -8 M/s 509 The apparent stead-state kinetic analysis of AuNPs@C.CNF were performed in a 1 mL of 0.5 M acetate buffer (pH 4.0) containing 20 μL of AuNPs@C.CNF as nano-enzyme and different concentration of H2O2 at fixed concentration of TMB or vice versa The reaction was monitored spectrophotometrically in time scan mode at 652 nm.The kinetic parameters were calculated by using the Michaelis-Menten equation, V = Vmax[S]/(Km+[S]), where V is the initial reaction velocity, Vmax is the maximal reaction velocity, and [S] substrate concentration and Km is the Michaelis constant. Km and Vmax were obtained by using Lineweaver-Burk plot equation, 1/V= (Km/Vmax) (1/[S]) + (1/Vmax).
