| 中文摘要 | bifunctional nanoarchitecture has been developed by combining the magnetic iron oxide and the luminescent ru(bpy)(3)(2+) encapsulated in silica. first, the iron oxide nanoparticles were synthesized and coated with silica, which was used to isolate the magnetic nanoparticles from the outer-shell encapsulated ru(bpy)(3)(2+) to prevent luminescence quenching. then onto this core an outer shell of silica containing encapsulated ru(bpy)(3)(2+) was grown through the stober method. highly luminescent ru(bpy)(3)(2+) serves as a luminescent marker, while magnetic fe3o4 nanoparticles allow external manipulation by a magnetic field. since ru(bpy)(3)(2+) is a typical electrochemiluminescence (ecl) reagent and it could still maintain such property when encapsulated in the bifunctional nanoparticle, we explored the feasibility of applying the as-prepared nanostructure to fabricating an ecl sensor; such method is simple and effective. we applied the prepared ecl sensor not only to the typical ru(bpy)(3)(2+) co-reactant tripropylamine (tpa), but also to the practically important polyamines. consequently, the ecl sensor shows a wide linear range, high sensitivity, and good stability. |
