Abstract
To improve the stability of pectin-oligochitosan hydrogel microcapsules under physiological conditions. Two different approaches were examined: change of the cross-linker length and treatment of the hydrogel microcapsules with 150 Mm CaCl2. Replacement of pectin with alginate was also studied. It was observed that the molecular weight of the cross-linker oligochiotsan had no significant improvement on microcapsule stability. On the other hand, the treatment of pectin-oligochitosan microcapsules with Ca2+ increased the microcapsule stability significantly. Different types of alginate were used; however, no red-blood-cell-shaped microcapsules could be produced, which is likely due to the charge-density difference between deprotonated pectin and alginate polymers.
