中文摘要 | we developed a stable, sensitive electrochemiluminescence (ecl) biosensor based on the synthesis of a new sol-gel material with the ion-exchange capacity sol-gel to coimmobilize the ru(bpy)(3)(2+) and enzyme. the partial sulfonated (3-mercaptopropyl)-trimethoxysilane sol-gel (pssg) film acted as both an ion exchanger for the immobilization of ru(bpy)(3)(2+) and a matrix to immobilize gold nanoparticles (aunps). the aunps/pssg/ru(bpy)(3)(2+) film modified electrode allowed sensitive the ecl detection of nadh as low as 1 nm. such an ability of aunps/pssg/ru(bpy)(3)(2+) film to promote the electron transfer between ru(bpy)(3)(2+) and the electrode suggested a new, promising biocompatible platform for the development of dehydrogenase-based ecl biosensors. with alcohol dehydrogenase (adh) as a model, we then constructed an ethanol biosensor, which had a linear range of 5 mu m to 5.2 mm with a detection limit of 12 nm. |
