Part 1: Filtering hydrogels
1) Pour top layer of safflower oil out of vials A1, B1, B2, C1, C2, D1, and D2
2) Add hexanes to each vial and vortex
3) Filter each hydrogel sample using vacuum filtration
4) Combine samples B1 and B2, C1 and C2, and D1 and D2
5) Re-disperse filtered hydrogels in phosphate buffer
Part 2: Observation of the addition of an acid/base to hydrogels containing indicators
