Abstract | Liposomes — microscopic phospholipid bubbles with a bilayered membrane
structure — have received a lot of attention during the past 30 years as pharmaceutical
carriers of great potential. More recently, many new developments have been seen in the area
of liposomal drugs — from clinically approved products to new experimental applications, with
gene delivery and cancer therapy still being the principal areas of interest. For further successful
development of this field, promising trends must be identified and exploited, albeit with a clear
understanding of the limitations of these approaches.
