Cross-linking through ionotropic gelation of sodium alginate with calcium chloride was employed to encapsulate the model drug indomethacin into the swellable multiple-unit calcium alginate microdisc(More)
Calcium alginate microdiscs were prepared by the gelification technique using sodium alginate as the precursor hydrophilic polymer and calcium chloride aqueous solution (1% w/v) as the cross-linking(More)
