CO2-triggered release from switchable surfactant impregnated liposomes

Incorporation of an amidine-based switchable surfactant into the lipid membrane of a liposome produces a system that is capable of triggered release upon in situ exposure to CO2. The amount of liposomal contents released is dependent on the concentration of switchable surfactant incorporated. A mechanism of the release is proposed. © 2014 the Partner Organisations.
