英文摘要 | a robust and effective composite film based on gold natioparticles (gnps)/room temperature ionic liquid (rtil)/multi-wall carbon nanotubes (mwnts) modified glassy carbon (gc) electrode was prepared by a layer-by-layer self-assembly technique. cytochrome c (cyt c) was successfully immobilized on the rtil-nanohybrid film modified gc electrode by electrostatic adsorption. direct electro-chemistry and electrocatalysis of cyt c were investigated. the results suggested that cyt c could be tightly adsorbed on the modified electrode. a pair of well-defined quasi-reversible redox peaks of cyt c was obtained in 0.10 m, ph 7.0 phosphate buffer solution (pbs). rtil-nanohybrid film showed an obvious promotion for the direct electron transfer between cyt c and the underlying electrode. the immobilized cyt c exhibited an excellent electrocatalytic activity towards the reduction of h2o2. the catalysis currents increased linearly to the h2o2 concentration in a wide range of 5.0 x 10(-5) - 1.15 x 10(-3) m. based on the multilayer film, the third-generation biosensor could be constructed for the determination of h2o2.
