摘要：

A direct electrochemical biosensing platform has been fabricated by covalent incorporation of carbon nanotubes (CNT) and gold nanoparticles (GNP) onto the poly(thionine) (PTH) film deposited by electropolymerization. With the synergic effects of the composite nanomaterials together with the excellent mediating redox polymer, the proposed platform could allow for faster electron transfer and higher enzyme immobilization efficiency than the platforms designed by using CNT or GNP alone. Comparison studies indicated that the as-developed H2O2 sensor could show greatly improved performances of amperometric responses.
