Cryo-TEM micrographs of the oil-free cubosomes based on MLO-
DGMO (
25). (a) Micrograph of dispersed cubosomes, (b) micrograph of a
cubosome when the electron beam was parallel to [100], and (c) the FFT corresponding
to (b). (d) Micrograph obtained when the electron beam was oriented along the [111]
direction, and (e) the FFT corresponding to (d). (f) The same particle as in (d) but after
tilting it 30° such that the electron beam was parallel to [110], and (g) the Fourier
transform of (f). The arrows in (d) and (f) indicate features that are likely to have come
from surface contamination. [Reprinted from Yaghmur et al. 2006b).]

The following points summarize our fi ndings with regard to the dispersed
and nondispersed oil - free systems:

Enhancement of the Water Solubilization Capacity
. The inclusion of
DGMO signifi cantly increased the water solubilization capacity for dis-
persed and nondispersed bulk MLO-DGMO-water phases. For instance,
