abstract = {Squalene based nanoparticles obtained via nanoprecipitation
are promising candidates as efficient anti-cancer drugs. In
order to highlight their preparation process and to
facilitate further clinical translation, the present study
enlightens the paramount role of the solvent in the
formation of these nanomedicines. Three different
squalene-based nanoparticles, i.e. squalenic acid,
deoxycytidine squalene and gemcitabine squalene, have been
investigated before and after organic solvent evaporation.
Size and structural analysis by Small Angle Neutron
Scattering revealed that droplets' size was uniquely
controlled by the solvent composition (ethanol–water),
which evolved during their gradual formation. The particles
were preferably swollen by water and the swelling increased
when less ethanol was present. Either coalescence or
fragmentation was observed depending on the increase or
decrease of the ethanol content, supporting an equilibrium
control of the size. Moreover, a high water swelling was
observed for the three local organization of the
nanodroplets (hexagonal for gemcitabine squalene, cubic for
deoxycytidine and not structured for squalenic acid) and
could be the source of the previously reported efficiency of
related anti-cancer squalene based nanomedicines.},
