Figure 11. Modular assembly of GAG based microcapsules by fusion.
Modular constructs were fabricated by perfusing packed capsules in a chamber of desired dimensions with diluted polymer solutions. This method yielded self-supporting constructs with uniform porosity. (A) Individual capsules in buffer solution before fusion. (B) Capsules being perfused with polymer solution in a perfusion chamber. Arrow indicates direction of flow. (C) Fused construct after removal from perfusion chamber.
