| 中文摘要 | in this contribution, we demonstrate a green, cost-effective, one-pot preparative route toward ag nanoparticles-graphene (agnps-g) nanocomposites in aqueous solution with the use of tannic acid (ta), an environmentally friendly and water-soluble polyphenol, as a reducing agent. such agnps-g nanocomposites were synthesized through one-pot reduction of agno3 and go by ta. we investigated surface enhanced raman scattering (sers) and electrochemical properties of the resultant agnps-g nanocomposites. it is found that such agnps-g nanocomposites show excellent sers activity as sers substrates and exhibit notable catalytic performance toward the reduction of h2o2. this enzymeless h2o2 sensor has a fast amperometric response time of less than 2 s. the linear range is estimated to be from 1 x 10(-4) m to 0.01m (r = 0.999) and the detection limit is estimated to be 7 x 10(-6) m at a signal-to-noise ratio of 3. a glucose biosensor was further fabricated by immobilizing glucose oxidase (god) into chitosan-agnps-g nanocomposite film on the surface of a glassy carbon electrode (gce). this sensor exhibits good response to glucose, and the linear response range is estimated to be from 2 to 10 mm (r = 0.996) at -0.5 v. the detection limit of 100 mu m was achieved at a signal-to-noise ratio of 3. more importantly, we demonstrate successfully its application for glucose detection in human blood serum. |
