Stimulus triggered release of actives from composite microcapsules based on sporopollenin from .

Smart drug delivery systems (SDDSs) are a paradigm shift in drug delivery, particularly in microencapsulation technology where the drug is released in response to an internal and/or external stimulus. In this study, a smart microencapsulation platform was developed using three different types of stimuli triggered release of a model active (rhodamine 6G) from sporopollenin from . Triggers were based on pH-, thermal- and near infrared light-sensitive polymer composition.
