    In Vitro Biomembrane Hybrid Systems 

    Biomembranes are amazing, multifunctional structures composed of a continuous bilayer of lipid molecules embedded with integral and peripheral membrane proteins. Membrane proteins make up ~30% of the genome of a typical eukaryotic cell, yet due largely to a strict requirement of a highly mobile, native-like biomembrane microenvironment, these molecules have not been widely built into functional materials.

    Membrane protein structure is often highly complex, typified by large, multi-subunit complexes that not only span the lipid bilayer but also contain large (>2 nm) cytoplasmic and extracellular domains that protrude from the membrane. We have been researching the construction of stabilized biomembrane hybrid systems based on a biomimetic, surface-tethered artificial cytoskeleton where membrane-protein-polymer bioconjugates anchor the lipid bilayer and provide adequate biomembrane to substrate spacing. This application of this core technology is to enable in vitro supported biomembrane systems in which membrane proteins with large cytoplasmic domains can be stably interfaced with materials. Furthermore, the anchoring of biomembranes in this fashion could lead to assemblies that could hold up to shear, flow, and friction in challenging microenvironments such as found in microdevices, packed beds, and biomaterials.
