Equilibrium fluctuations of a quasi-spherical vesicle: role of the membrane dissipation

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.
