Optimizing the Performance of Supported Lipid Bilayers as Cell Culture Platforms Based on Extracellular Matrix Functionalization.

ABSTRACT: Strategies to fabricate biofunctionalized surfaces are essential for many biotechnological applications. Zwitterionic lipid bilayer coatings doped with lipids with chemically selective headgroups provide a robust platform for immobilization of biomolecules in an antifouling, protein resistant background. Herein, we assess the biological activity of two important components of the extracellular matrix (ECM), collagen type I (Col I) and fibronectin (FN), which are covalently attached to a supported lipid bilayer (SLB), and compare their activity with the same proteins, nonspecifically adsorbed onto a SiO₂ surface. The characterization of protein coatings by quartz crystal microbalance with dissipation revealed that Col I and FN attached to SLB are less dense and have higher struct
