| 中文摘要 | the facile synthesis of the novel platinum nanoparticles/eastman aq55d/ruthenium(ii) tris( bipyridine) (ptnps/ aq/ru(bpy)(3)(2+)) colloidal material for ultrasensitive ecl solid-state sensors was reported for the first time. the cation ion-exchanger aq was used not only to immobilize ecl active species ru(bpy)(3)(2+) but also as the dispersant of ptnps. colloidal characterization was accomplished by transmission electron microscopy (tem), x-ray photoelectron spectrum (xps), and uv-vis spectroscopy. directly coating the as-prepared colloid on the surface of a glassy carbon electrode produces an electrochemiluminescence (ecl) sensor. the electronic conductivity and electroactivity of ptnps in composite film made the sensor exhibit faster electron transfer, higher ecl intensity of ru(bpy)(3)(2+), and a shorter equilibration time than ru(bpy)(3)(2+) immobilized in pure aq film. furthermore, it was demonstrated that the combination of ptnps and permselective cation exchanger made the sensor exhibite excellent ecl behavior and stability and a very low limit of detection (1 x 10(-15) m) of tripropylamine with application prospects in bioanalysis. this method was very simple, effective, and low cost. |
