(a) Ellipsometric thicknesses of APTES, biotin-BSA, avidin and a dispersion of vesicles deposited sequentially onto a silicon wafer. The biotin-free vesicles were composed of 99% DOPC, 1% BODIPY-DHPE; the biotinylated vesicles were composed of 98% DOPC, 1% biotin-DOPE, 1% BODIPY-DHPE. (b) Plot of epifluorescence intensity measured following incubation of an avidin-functionalized glass slide in a dispersion of vesicles. (c). Plot of lipid density measured following incubation of an avidin-functionalized glass slide in a dispersion of vesicles. The error bars represent one standard deviation. (N=4)
