제목 Bioelectrochemical Characterization of Carbon Nanotube/Ionic Liquid Bucky Gel Electrode for Biosensor
초록 Herein, we report about the immobilization of organophosphorus hydrolase (OPH) on multi-walled carbon nanotube (MWNT)/IL bucky gel electrode for the application into biosensors. The MWNT/IL bucky gels were formed by grinding the mixture of 20 mg MWNTs and 0.2 mL 1-butyl-3-methylimidazolium tetrafluoroborate (BMimBF4) IL with an agate mortar for about 20 min. The morphology of as-obtained MWNT/IL/OPH electrode was observed by SEM. The electrochemical properties of pristine MWNT, MWNT/IL, MWNT/OPH, and MWNT/IL/OPH electrode were characterized by cyclic voltammetry. The electron transfer rate of MWNT/IL/OPH electrode was higher than those of other electrodes due to the synergetic promotion of MWNTs and ILs to electron transfer, especially the IL as the binder, exhibiting better electrochemical properties.
