- Sporopollenin microcages were obtained from pollens of Platanus orientalis tree.
- Analgesic drug paracetamol was encapsulated into the sporopollenin microcages.
- The encapsulation efficiency of the passive loading technique was found as 8.2%.
- The encapsulation efficiency of the evaporating loading technique was found as 23.7%.
- Paracetamol-loaded sporopollenin microcages showed a more controlled release.
Sporopollenin microcages were produced from the pollens of Platanus orientalis. Paracetamol was loaded into the microcages. Pollen, sporopollenin, paracetamol and paracetamol-loaded sporopollenin microcages were characterized with FT-IR, TGA and SEM. The analytical analyses demonstrated that sporopollenin microcages were structurally intact, highly reticulated and thermally stable. The loading efficiency of the sporopollenin microcages was found to be 8.2% using the passive loading technique and 23.7% via evaporating loading technique. In vitro release and kinetics studies were performed to test the suitability of sporopollenin microcages for loading. These studies revealed that sporopollenin from P. orientalis can be suggested as a suitable carrier for drug loading and controlled release studies.
