- W2039903143 abstract "A novel H2O2 biosensor has been fabricated based on the direct electrochemistry and electrocatalysis of myoglobin (Mb) immobilized on silver nanoparticles doped carbon nanotubes film with hybrid sol–gel techniques. A pair of redox peaks with peak separation of 160 mV and formal potential of −0.295 V was observed at this composite film, corresponding to the direct electrochemistry of Mb. The heterogeneous rate constant was estimated to be 0.41 s−1. Under optimum conditions, the amperometric determination of H2O2 was performed with a linear range of 2.0 × 10−6–1.2 × 10−3 mol L−1 and a detection limit of 3.6 × 10−7 mol/L (S/N = 3). The Michealis–Menten constant was also estimated to be 1.62 mmol L−1. The proposed biosensor showed favorable reproducibility, stability, selectivity and accuracy, and has been used to determine H2O2 in real samples with favorable recoveries." @default.
