Atomic force microscopy and other scanning probe microscopy methods to study nanoscale domains in model lipid membranes

Advances in Physics: X, 2023
The cell membrane is a fundamental biological structure, which is only 6–10 nm thick. It is composed of hundreds of lipid types, which form small and dynamic lipid domains or rafts.

Unraveling membrane properties at the organelle-level with LipidDyn

Computational and Structural Biotechnology Journal, 2022
Cellular membranes are formed from different lipids in various amounts and proportions depending on the subcellular localization. The lipid composition of membranes is sensitive to changes in the cellular environment, and its alterations are linked to ...

Concise theory of chiral lipid membranes [PDF]

, 2007
A theory of chiral lipid membranes is proposed on the basis of a concise free energy density which includes the contributions of the bending and the surface tension of membranes, as well as the chirality and orientational variation of tilting molecules ...

Membrane Flotation Assay

Bio-Protocol, 2015
Many postitive-stranded RNA viruses, such as Hepatitis C virus (HCV), highjack cellular membranes, including the Golgi, ER, mitchondria, lipid droplets, and utilize them for replication of their RNA genome or assembly of new virions. By investigating how

Exploring the Impact of Lipid Domain Size on the Lifetime: A Dissipative Particle Dynamics Study

East European Journal of Physics, 2023
In this research, we have used the dissipative particle dynamics (DPD), a mesoscopic simulation technique, in order to investigate the dynamics of lipid domains in near critical temperature. Our specific focus has been on exploring the influence of lipid

Mixed lipid bilayers with locally varying spontaneous curvature and bending

, 2014
A model of lipid bilayers made of a mixture of two lipids with different average compositions on both leaflets, is developed. A Landau hamiltonian describing the lipid-lipid interactions on each leaflet, with two lipidic fields $\psi_1$ and $\psi_2$, is ...
