Chitosan alginate capsules

Patent Pending Several groups have also investigated the use of chitosan which is a naturally derived polycation as a potential replacement for PLL to fabricate alginate-chitosan (AC) microcapsules for cell delivery applications.[28][29] However, studies have also shown that the stability of this AC membrane is again limited[30][31] and one group demonstrated that modification of this alginate-chitosan microcapsules with genipin, a naturally occurring iridoid glucosid from gardenia fruits, to form genipin cross-linked alginate-chitosan (GCAC) microcapsules could augment stability of the cell loaded microcapsules.
