Leaflet Tensions Control the Spatio-Temporal Remodeling of Lipid Bilayers and Nanovesicles
Lipowsky, Reinhard; Ghosh, Rikhia; Satarifard, Vahid; Sreekumari, Aparna; Zamaletdinov, Miftakh; Różycki, Bartosz; Miettinen, Markus; Grafmüller, Andrea (Journal article; Peer reviewed, 2023)Biological and biomimetic membranes are based on lipid bilayers, which consist of two monolayers or leaflets. To avoid bilayer edges, which form when the hydrophobic core of such a bilayer is exposed to the surrounding ... -
Probing the elastic response of lipid bilayers and nanovesicles to leaflet tensions via volume per lipid
Zamaletdinov, Miftakh F.; Miettinen, Markus; Lipowsky, Reinhard (Journal article; Peer reviewed, 2023)Biological and biomimetic membranes are based on lipid bilayers, consisting of two monolayers or leaflets. One important but challenging physical parameter of these membranes is their tension. For a long time, this tension ... -
Quantitative Comparison against Experiments Reveals Imperfections in Force Fields’ Descriptions of POPC-Cholesterol Interactions
Javanainen, Matti; Heftberger, Peter; Madsen, Jesper J.; Miettinen, Markus; Pabst, Georg; Ollila, O. H. Samuli (Journal article; Peer reviewed, 2023)Cholesterol is a central building block in biomembranes, where it induces orientational order, slows diffusion, renders the membrane stiffer, and drives domain formation. Molecular dynamics (MD) simulations have played a ... -
Structure of POPC Lipid Bilayers in OPLS3e Force Field
Kurki, Milla; Poso, Antti; Bartos, Piia; Miettinen, Markus (Journal article; Peer reviewed, 2022)It is crucial for molecular dynamics simulations of biomembranes that the force field parameters give a realistic model of the membrane behavior. In this study, we examined the OPLS3e force field for the carbon−hydrogen ...
