This dataset contains the data for the results presented in this publication on model bacterial cell membranes. The measurements included: pressure-area isotherm data, electrochemical data and infrared spectroscopy (PM-IRRAS) data for bilayers, Brewster Angle Microscopy (BAM) data for monolayers, Grazing Incidence X-ray Diffraction (GIXD) and X-Ray Reflectivity (XRR) data for monolayers and Neutron Reflectivity (NR) data for monolayers.
