Week 3: 4/15 - 4/21

  8:34 AM    No comments
This week we presented our methodology of our alginate-chitosan layered capsule as a PowerPoint presentation. Calcium alginate beads will be created from dripping sodium alginate into calcium chloride solution. Therapeutics will be encapsulated into the beads via rotary die or mixing. Chitosan will be coated on the calcium alginate beads using the Polyelectrolyte Multilayer Method (PEM). Essentially, the beads will be quickly dipped into chitosan solution and washed, forming a thin film of polyelectrolyte complex.
