ObjectiveDescriptionPart A:Preparing hydrogels for pH analysis
-Measure the absorbance of each supernatant to find the amount of CV that the hydrogels have absorbed 2) Prepare 2 more hydrogel solutions with the following indicators (these will be used to measure dye leakage as well as to monitor pH changes) a) methyl red (55μL) in 1.5 mL ethanol w/ 2mg hydrogels b) bromophenol blue (30μL) in 1.5 mL water w/ 2mg hydrogels DataNotes |
