The ion channels of membrane properties induced by PF -6 were studied by the cyclic voltammetric methods. Experimental results indicated that the ion channel of BLM was open in the presence of the PF -6 due to the interaction of PF -6 with the BLM, while it was switched off in the absence of PF -6. Because the ion channel behavior was affected by the concentration of PF -6, a sensor for PF -6 can be developed.展开更多
