In a recent paper, we hypothesized that the continuous increase in membrane conductance observed for nano-BLMs is the result of an independent rupturing of single membranes or membrane patches covering the pores of the porous material. To prove this hypothesis, we prepared micro-BLMs on porous
Charge-pulse experiments were performed with lipid bilayer membranes from oxidized cholesterol/n-decane at relatively high voltages (several hundred mV). The membranes show an irreversible mechanical rupture if the membrane is charged to voltages on the order of 300 mV. In the case of the mechanical
The effect of endotoxin fromSalmonella typhimurium orEscherichia coli was studied on bilayer lipid membranes (1% lecithin-1% cholesterol in n-decane) formed in buffered 0.1M NaCl solution (pH 6.8). Endotoxin was added to the buffered solution either prior to membrane formation or after stable
