Objectives Sonicate hydrogels containing dye using ultra sonic liquid processing and filter (2x) Mix sonicated hydrogels containing no dye with dye and indicators to monitor absorbance Procedures Part 1: Sonication of Hydrogels 1) Measure ~7.5mL of solution C 2) Sonicate for ~5 minutes at 15 watts 3) Filter using vacuum filtration (Filter used: Quantitative P8, Porosity: Coarse, Flow Rate: Fast) 4) Filter the filtrant once more through a nylon filter. 5) Take absorbance of remaining filtrant 6) Redisperse hydrogels on filter paper back into 10 mL phosphate buffer and observe under microscope Part 2: Mixing ultrasonicated hydrogels The following samples were prepared: Data Add data and results here...
