Lipid Research (IMAGE) University of Texas at Dallas Caption University of Texas at Dallas scientists developed a method to stabilize liposomes in a crystalline exoskeleton, which allows the biomolecules to remain stable at room temperature. This illustration depicts a proteoliposome -- a spherical bilayer of fat molecules (white and blue) -- stabilized in a structure called a zeolitic-imidazole framework composed of zinc acetate and methylimidazole. Inserted into the lipid bilayer -- which mimics a cell membrane -- are modeled structures of CopA proteins, with a section (in pink) that resides inside the lipid and sections above the lipid surface (brown) and slightly inside the liposome (also brown, but inside).
