将整个活的荧光假单胞菌细胞固定在用基于噻吩的导电聚合物修饰的石墨电极上。用透析膜将细菌细胞包埋在导电共聚物基质上制成微生物电极。以葡萄糖为底物对该传感器进行了表征。以及分析表征，电聚合时间，pH值和温度对传感器响应的影响进行了研究。最后，还测试了操作稳定性。(c)2008爱思唯尔有限公司保留所有权利。
Immobilization of whole viable Pseudomonas fluorescens cells was achieved on a graphite electrode modified with a thiophene-based conducting polymer. Microbial electrodes were constructed by the entrapment of bacterial cells on conducting copolymer matrix using a dialysis membrane. The biosensor was characterized using glucose as the substrate. As well as analytical characterization, effects of electropolymerization time, pH and temperature on the sensor response were examined. Finally, operational stability was also tested.
