Objectives

-Suspend hydrogels back into solution

-Attach dye to hydrogels once they are in solution

-Measure the amount of dye absorbed

Procedures

1) Add 0.1 g of hydrogel (1 sample with lecithin and one without) in 5mL phosphate buffer

2) Sonicate for ~25 minutes or until hydrogels have separated

3) Add 5 μL of dye.

4) Allow hydrogels to absorb dye overnight

5) Calculate the amount of dye absorbed by the hydrogels by measuring the concentration left in solution
