Asymmetric Lipid Bilayer

Asymmetric Lipid Bilayer

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%...

Background:

Bionics-inspired materials are crucial for medical devices but often require multifunctional coatings.
Existing materials may not meet the complex demands of specific service environments.

Purpose of the Study:

To design and characterize a phospholipid-based multifunctional coating.
To evaluate the coating's biocompatibility, focusing on hemocompatic and cellular interactions.

Main Methods:

Layer-by-layer assembly of phospholipid-based polymers, collagen type I (Col-I), and REDV peptide.
Characterization using FTIR, 1H NMR, UV-Vis, XPS, QCM, WCA, and AFM.
In vitro assessment of platelet adhesion, activation, smooth muscle cell (SMC), and endothelial cell (EC) behavior.

Main Results:

Successful synthesis and characterization of the multifunctional coating.
Demonstrated inhibition of platelet adhesion and SMC proliferation.
Analysis confirmed coating hydrophilicity and controlled roughness.

Conclusions:

The developed multifunctional coating exhibits significant anticoagulant and cell-compatible properties.
This coating shows promise for blood-contacting medical devices like cardiovascular stents.
