Area of Science:

• Biophysics
• Materials Science
• Polymer Physics

Background:

• Controlling vesicle shape is crucial for biophysics and materials design.
• Soft vesicles are essential structures in biological systems and synthetic materials.

Purpose of the Study:

• Investigate the shape transformations of soft vesicles induced by external semiflexible polymers in a 2D environment.
• Analyze the impact of polymer bending stiffness and vesicle-polymer attraction strength on vesicle morphology.

Main Methods:

• Utilized the Monte Carlo simulation method to model vesicle-polymer interactions.
• Performed simulations in a two-dimensional system to observe shape dynamics.

Main Results:

• Vesicle shape is significantly influenced by polymer bending stiffness (κ) and the attractive interaction strength (εVP).
• Observed diverse vesicle shapes including circular, cigar-like, double vesicle, and racquet-like morphologies.
• Demonstrated that varying κ and εVP allows for predictable control over vesicle geometry.

Conclusions:

• The study provides a computational framework for understanding and predicting vesicle shape control.
• Engineering vesicle shapes through polymer interactions opens possibilities for tailored applications in materials science and nanotechnology.
