中文摘要	a sol-gel derived ceramic-carbon composite electrode is used for fabrication of a new type of optical fiber biosensor based on luminol electrochemiluminescence (ecl). the electrode consists of graphite powder impregnated with glucose oxidase in a silicate network. in this configuration, the immobilized enzyme oxidizes glucose to liberate hydrogen peroxide and graphite powder provides percolation conductivity for triggering the ecl between luminol and the liberated hydrogen peroxide. both of the reactions occur simultaneously on the surface of the composite electrode, thereby the response of the biosensor is very fast. the peak intensity was achieved within only 20 s after glucose injection. in addition, the electrode could be renewed by a simple mechanical polishing step in case of contamination or fouling. the linear range extends from 0.01 to 10 mm for glucose and the detection limit is about 8.16 mum. the renewal repeatability and stability of the biosensor are also investigated in detail.
