Solvent Driven Formation of Bolaamphiphilic Vesicles
M. I. Katsnelson, A. Fasolino
TL;DR
This paper investigates how solvent interactions induce the spontaneous formation of bolaamphiphilic vesicles, demonstrating their stability and deformation behavior under magnetic fields using theoretical models.
Contribution
It introduces a theoretical framework explaining vesicle formation driven by solvent interactions and analyzes vesicle deformation in magnetic fields.
Findings
Vesicle formation results from core-core and tail-solvent interaction competition.
Spherical vesicles are stable under broad interaction conditions.
Vesicle deformation in magnetic fields aligns with recent experimental observations.
Abstract
We show that a spontaneous bending of single layer bolaamphiphiles results from the frustration due to the competition between core-core and tail-solvent interactions. We find that spherical vesicles are stable under rather general assumptions on these interactions described within the Flory-Huggins theory. We consider also the deformation of the vesicles in an external magnetic field that has been recently experimentally observed.
