Abstract
Some electrical properties were studied on potential responses of self-assembled bilayer lipid membranes (s-BLMs). Gramicidin doped s-BLM sensors responded to hydrogen ion concentrations linearly with the slope of 144 mV/decade in the range of 0.4 to 4 M; Monensin doped s-BLM sensors responded to sodium ion, which has a slope of about 40 mV/decade in the concentration range of 0.3 to 30 mM; Valinomycin doped s-BLM sensors have nearly Nernstian response in the concentration range of 1.0 to 30 mM/[K+]; Ferrocene doped s-BLM sensors responded linearly to the ferricyanide ion, whose slope is 146 mV/decade in the concentration range of 0.03 to 30 mM/[K3Fe(CN)6]. Many ions such as ferrocyanide, citrate, SCN-, ClO4/$(superscript -, etc. did not interfere with the sensor response characteristics. Factors influencing s-BLM sensors' reproducibility and stability also were investigated.
