Sulfited Tannin Capsules: Novel Stimuli-Responsive Delivery Systems

Microcapsules of sulfited Acacia mearnsii tannin (AmST-MCs) were generated for the first time via sonochemical method. Their stability profile was assessed and set in general context microcapsules (TMCs) under same experimental conditions. The analytical data gathered this work indicate an excellent TMCs over as well high temperature pressure, which is a major milestone toward meaningful applications industrial, pharmaceutical, biomedical sterilization might be prerequisite. Active release shown to efficiently triggered by varying pH and/or salinity, with different profiles from nonsulfited species. Surfactants also affect significantly, effects eventually amplifiable inherent kosmotropic chaotropic characteristics salt components solutions.
