Measuring Activation Energies for Ion Transport Using Tethered Bilayer Lipid Membranes (tBLMs),Model lipid bilayers tethered to a gold substrate with molecular tethers are constructed. The conductance versus temperature dependence curve is then obtained. Here, a method to measure the activation energy for translocation of an ion through existing transmembrane pores in a sparsely tethered bilayer lipid membranes is presented.

Establishing a Lipid Bilayer for Molecular Dynamics Simulations,Lipid bilayers play a very important role in every living organism. Generating a computer model for simulations provides a molecular scale picture that can unveil information difficult to obtain using traditional experiments. Here, a procedure to generate a computer model of a stable lipid bilayer structure is discussed.

Langmuir-Schaefer Deposition to Create an Asymmetrical Lipopolysaccharide Sparsely Tethered Lipid Bd bilayers such as black lipid membranes (BLMs) (Cranfield et al. Biophys J 106:182–189, 2014). The challenge to rapidly create asymmetrical tBLMs that include a lipopolysaccharide outer leaflet for bacterial model membrane research can be overcome by the use of a Langmuir-Schaefer deposition protoc

Determining the Pore Size of Multimeric Peptide Ion Channels Using Cation Conductance Measures of Tability of ions in real-time (Deplazes et al. J Phys Chem Lett 11:6353–6358, 2020). Conductance readings, as determined by EIS, are a measure of the ability of ions to be transported across membranes. Recording the change in conductance as a function of cation concentration and a comparison between
