Separation of gold nanocrystal-loaded DOPC vesicles from nanocrystal-free vesicles. High speed centrifugation (10,000g for 60 minutes) precipitates the heavier nanocrystal-loaded vesicles from the nanocrystal-free vesicles. The vesicle mass was determined by assuming that lipids occupy an area of 0.7 nm2 with a 4 nm thick lipid bilayer,37 with nanocrystals residing at the center of the lipid bilayer and occupying an area of 10 nm2, based on LB nanocrystal monolayers (Figure 11).48 The nanocrystal molecular weight was taken to be 50 kDa/nanocrystal based on the TGA measurement of the ligand content.
