摘要
Bilayer lipid membranes (BLM) formed from didodecyldimethylammonium bromide were made on the freshly exposed surface of a glassy carbon (GC) and were demonstrated by the ac impedance spectroscopy. 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.
