In this paper, supported bilayer lipid membrane (s-BLM) was served as a biomembrane model. The interaction between sodium deoxycholate (NaDC) and s-BLM was investigated by means of cyclic voltammetry and ac impedance spectroscopy.

• 以支撑磷脂双层膜(supported bilayer lipid membrane；s-BLM)作为生物膜模型；采用循环伏安法和交流阻抗技术研究了脱氧胆酸钠(sodium deoxycholate；NaDC)与s-BLM的相互作用.
