Week 5: 4/29 - 5/5

This week, we ordered our materials for the production of chitosan layered alginate beads. Specifically, we ordered 50 mL of chitosan solution (which we will dilute to 3% w/v), a syringe with size-22 needle, several 50 mL and 100 mL beakers, and filter paper. Everything arrived on 5/5, except the syringe, which will arrive on 5/9. Sodium alginate, calcium chloride, and water will be provided for us in lab. Instead of encapsulating antacids, we are encapsulating food coloring. The rationale behind this change is because antacids are difficult to see, whereas food coloring is easy to detect with the naked eye; this will ease the testing of diffusion rates.
