| 中文摘要 | in this paper, we report on the first preparation of well-defined sio(2)-coated graphene oxide (go) nanosheets (sio(2)/go) without prior go functionalization by combining sonication with sol-gel technique. the functional sio(2)/go nanocomposites (f-sio(2)/go) obtained by surface functionalization with nh(2) group were subsequently employed as a support for loading ag nanoparticles (agnps) to synthesize agnp-decorated f-sio(2)/go nanosheets (agnp/f-sio(2)/go) by two different routes: (1) direct adsorption of preformed, negatively charged agnps; (2) in situ chemical reduction of silver salts. the morphologies of these nanocomposites were characterized by transmission electron microscopy (tem) and scanning electron microscopy (sem). it is found that the resultant agnp/f-sio(2)/go exhibits remarkable catalytic performance for h(2)o(2) reduction. this h(2)o(2) sensor has a fast amperometric response time of less than 2s. the linear range is estimated to be from 1 x 10(-4) m to 0.26 m (ry = 0.998) and the detection limit is estimated to be 4 x 10(-6) mat a signal-to-noise ratio of 3, respectively. we also fabricated a glucose biosensor by immobilizing glucose oxidase (god) into agnp/f-sio(2)/go nanocomposite-modified glassy carbon electrode (gce) for glucose detection. our study demonstrates that the resultant glucose biosensor can be used for the glucose detection in human blood serum.
