碘修饰的S-BLM生物传感器研究

Studies on S-BLM Biosensors Modified with Iodine

从关注金属表面的机械特性角度出发 ,初步探讨了金属表面对 BL M膜稳定性的影响。采用一种简单的方式处理多根空白电极 ,并用循环伏安法对其进行测试 ,获得比较一致的测量结果 ;测试了未经修饰的双分子层膜电极以及经碘分子修饰的双分子层膜电极的伏安特性 ,发现经碘分子修饰的双分子层膜电极能响应不同浓度的碘离子溶液 ;在一定范围内 。

The effect of metal surface on the stabilization of S BLM was studied by modifying blank electrodes with iodine molecules in a simple way and then comparing their cyclic voltammetric measurement with those blank electrodes without iodic modification. Results obtained indicate that S BLM electrodes modified with iodine can response to solution of iodide ions at different concentrations, and that the charges measurement are nearly linear with the concentration within a certain range.
