Abstract: As a kind of supported bilayer lipid membranes, hybrid bilayer membrane(HBM) was applied to the interaction between Ca 2+ and lipid for the first time. By using Fe(CN)63- as a probe, we found that Ca 2+ coulDInduce the ion channel of HBMto be in open state. STMimages study proved this phenomenon.
