| 中文摘要 | the hydrophobic carbon nanotubes-ionic liquid (cnts-il) get forms a stable modified film on hydrophobic graphite electrode surface. laccase immobilized on the cnts-il gel film modified electrode shows good thermal stability and enhanced electrochemical catalytic ability. the optimal bioactivity occurs with increasing temperature and this optimum is 20 degrees c higher in comparison to free laccase. the improvement of laccase thermal stability may be due to the microenvironment of hydrophobic cnts-il gel on graphite electrode surface. on the other hand, the sensitive detection of oxygen has been achieved due to the feasibility of oxygen reduction by both of laccase and nanocomposite of cnts-il gel. furthermore, the laccase hybrid nanocomposite also shows the fast electrochemical response and high sensitivity to the inhibitors of halide ions with the approximate ic50 of 0.01, 4.2 and 87.5 mm for the fluoride, chloride and bromide ions, respectively. it implies the feasibility of laccase modified electrode as an inhibition biosensor to detect the modulators of laccase. |
