Summary
This study introduces a microfluidic jetting method for creating and loading giant unilamellar vesicles (GUVs). This technique enables repeatable encapsulation of diverse contents, advancing biomolecular compartmentalization for research and therapies.
Area of Science:
- Biophysics
- Materials Science
- Biotechnology
Background:
- Compartmentalization of biomolecules in lipid membranes is crucial for life and therapeutics.
- Current methods for creating unilamellar vesicles with controlled contents are limited in repeatability and scalability.
Purpose of the Study:
- To develop a novel method for simultaneous creation and loading of giant unilamellar vesicles (GUVs).
- To overcome limitations in forming repeatable, monodisperse GUVs with controlled contents.
Main Methods:
- Utilized a pulsed microfluidic jet to deform a planar lipid bilayer into a vesicle.
- The jet simultaneously fills the forming vesicle with a desired solution.
Main Results:
- Demonstrated rapid generation of multiple monodisperse, unilamellar vesicles.
- Successfully encapsulated 500-nm particles and functional pore proteins into GUVs.
- Showcased unrestricted composition and molecular weight loading capabilities.
Conclusions:
- Microfluidic jetting offers a controllable and repeatable method for GUV formation and loading.
- This technique opens new avenues for studying and utilizing compartmentalized biomolecular systems.
- Potential applications span scientific research, industry, and medicine.
