Effect of CM15 on Supported Lipid Bilayer Probed by Atomic Force Microscopy
Membranes, 2023 Antimicrobial peptides are key components of the immune system. These peptides affect the membrane in various ways; some form nano-sized pores, while others only produce minor defects.

Correlated diffusion in lipid bilayers [PDF]
Proceedings of the National Academy of Sciences, 2021 SignificanceDynamic processes on membrane surfaces are essential for biological function. Traditionally, quantitative measurements of lipid/protein motion have been interpreted in the framework of membrane hydrodynamics. However, some recent single-molecule tracking studies have proven difficult to interpret via hydrodynamic arguments.

Measuring anion binding at biomembrane interfaces
Nature Communications, 2022 Quantification of anion binding by molecular receptors within lipid bilayers is challenging. Here, the authors synthesise a high-affinity macrocyclic anion receptor which provides insights into determinants of anion binding within lipid bilayers.

Water Pores in Planar Lipid Bilayers at Fast and Slow Rise of Transmembrane Voltage
Membranes, 2021 Basic understanding of the barrier properties of biological membranes can be obtained by studying model systems, such as planar lipid bilayers. Here, we study water pores in planar lipid bilayers in the presence of transmembrane voltage.

Structure and drug binding of the SARS-CoV-2 envelope protein transmembrane domain in lipid bilayers
Nature Structural & Molecular Biology, 2020 An essential protein of the SARS-CoV-2 virus, the envelope protein E, forms a homopentameric cation channel that is important for virus pathogenicity.

Glycophorin in Lipid Bilayers [PDF]
Proceedings of the National Academy of Sciences, 1974 Glycophorin, the major glycoprotein of human erythrocytes, has been isolated and reincorporated into lipid vesicles. Freeze-fracture electron microscopy shows the reincorporated glycophorin to occur as small particles in vesicle fracture faces while the etch faces are smooth.

Insight into the interactions, residue snorkeling, and membrane disordering potency of a single antimicrobial peptide into different lipid bilayers. [PDF]
PLoS ONE, 2017 Pardaxin, with a bend-helix-bend-helix structure, is a membrane-active antimicrobial peptide that its membrane activity depends on the lipid bilayer composition.

Volumetric stability of lipid bilayers [PDF]
Physical Chemistry Chemical Physics, 2012 In agreement with recent reports, a commercial densimeter has yielded a gradual decrease in lipid molecular volume of DPPC multilamellar vesicle dispersions in the gel phase upon repeated thermal cycling between 10 °C and 50 °C. The considerable size of this decrease would have significant implications for the physical chemistry of biomembranes.

Composition Fluctuations in Lipid Bilayers [PDF]
Biophysical Journal, 2016 AbstractLipid bilayers constitute the basis of biological membranes. Understanding lipid mixing and phase behavior can provide important insights into membrane lateral organization (the “raft” hypothesis). Here we investigate model lipid bilayers below and above their miscibility transition temperatures.
