Summary
Asymmetric unilamellar vesicles, models for cell membranes, are now easier to create using microfluidics. This review explores methods to generate these complex vesicles for biomedicine.
Area of Science:
- Biomaterials Science
- Nanotechnology
- Chemical Engineering
Background:
- Asymmetric unilamellar vesicles (AUVs) are crucial models for cell membranes and hold potential for biomedicine.
- Their complex structure, with dissimilar leaflets, has limited widespread study and application.
- Generating asymmetric membranes is a significant challenge in vesicle fabrication.
Approach:
- This review focuses on microfluidic techniques for high-throughput AUV fabrication.
- It covers methods for creating asymmetric lipid vesicles and lipid-polymer vesicles.
- Non-microfluidic methods for AUV generation are also briefly reviewed.
Key Points:
- Microfluidics offers advanced, high-throughput solutions for fabricating asymmetric vesicles.
- The review details methods for both lipid-only and lipid-polymer asymmetric membranes.
- Diverse fabrication techniques are presented to facilitate wider adoption.
Conclusions:
- Recent advances, particularly in microfluidics, have significantly improved the ability to generate asymmetric vesicles.
- The review aims to encourage broader scientific adoption of these advanced fabrication methods.
- Wider use of AUVs can accelerate progress in cell membrane modeling and biomedicine.

7.4K
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...

3.2K
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...
