Emulsification preparation of calcium alginate beads in the presence of sequesterant.


A biocompatible emulsification method has been developed for microencapsulation of live cells and enzymes within a calcium alginate matrix. Fabrication of alginate beads was achieved by premixing a sequestering agent (sodium polyphosphate) and the calcium source (calcium sulphate) with the hydrogel monomer prior to the introduction to the oil phase.
