Identity and location in the temperature-composition phase diagram of
MLO-water as determined by small-angle X-ray scattering (SAXS) in the heating
direction between 20 and 94°C (de Campo et al., 2004). The black guidelines bring into
evidence the phase transitions and regions of coexistence between the mesophases. The
gray line corresponds to the phase separation line between the single-phase regions
(left) and the biphasic systems: self-assembled nanostructures coexisting with excess
water (right).
water-in-oil (W/O) emulsion in double W/O/W emulsions, by kinetically dis-
persed droplets confi ning thermodynamically stable nanostructures. In other
words, we aimed to detect the infl uence of various parameters on
ISAsomes
(
internally self-assembled particles or somes
), which are aqueous dispersions
of a family of colloidal droplets (cubosomes, hexosomes, micellar cubosomes,
and emulsifi ed microemulsions) with internal self-assembled nanostructures.
Owing to their unique physicochemical properties, these nonviscous emulsion
nanoobjects are superior to conventional dispersions (emulsions, double emul-
sions, and liposomes).
There is a huge surge of interest in utilizing nanostructured emulsions in a
variety of applications due to their possible biological relevance, their high
interfacial area, and their capacity to solubilize hydrophilic, amphiphilic, and
hydrophobic active guest molecules with biological and pharmaceutical rele-
vance (Boyd, 2005; Drummond and Fong, 2000; Larsson, 2009; Leser et al.,
2006; Malmsten, 2006; Mezzenga et al., 2005; Siekmann et al., 2002; Yaghmur
and Glatter, 2009). For instance, potential applications include nanoreactors
or host nanoparticulate delivery systems in the cosmetic, pharmaceutical, and
food industries.
