| 中文摘要 | a novel electrogenerated chemiluminescence (ecl) sensor based on ru(bpy)(3)(2+)-doped silica (ruds) nanoparticles conjugated with a biopolymer chitosan membrane was developed. these uniform ruds nanoparticles ( similar to 40 nm) were prepared by a water-in-oil microemulsion method and were characterized by electrochemical and transmission electron microscopy technology. the ru( bpy)(3)(2+)-doped interior maintained its high ecl efficiency, while the exterior nanosilica prevented the luminophor from leaching out into the aqueous solution due to the electrostatic interaction. this is the first attempt to branch out the application of ruds nanoparticles into the field of ecl, and since a large amout of ru(bpy)(3)(2+) was immobilized three-dimensionally on the electrode, the ru( bpy)(3)(2+) ecl signal could be enhanced greatly, which finally resulted in the increased sensitivity. this sensor shows a detection limit of 2.8 nm for tripropylamine, which is 3 orders of magnitude lower than that observed at a nafion-based ecl sensor. furthermore, the present ecl sensor displays outstanding long-term stability. |
