Key Points

This study aims to explore the relationship between membrane dissipation and curvature fluctuations in quasi-spherical vesicles.
Theoretical modeling was employed to analyze the effects of thermal energy on vesicle curvature and lipid density fluctuations.
Key factors considered include monolayer viscosity and intermonolayer friction in the calculations.
Predictions indicate that increased membrane dissipation leads to enhanced curvature fluctuations.
Lipid density fluctuations are also influenced by the dissipation mechanisms considered in the model.

Implication

Theoretical investigation reveals effects of membrane dissipation on vesicle fluctuations, suggesting pivotal insights into cellular behavior.

Abstract

We theoretically investigate the thermally-driven curvature and lipid density fluctuations of a quasi-spherical vesicle, accounting for the dissipation due to monolayer viscosity and intermonolayer friction. The theory predicts that membrane...
