*Each of the samples had a very fast diffusion rate. If the spectra are viewed additively for each hydrogel sample, a significant amount of dye leaked out of the hydrogel sample in only 2 hours, in comparison to the hydrogels which remained in distilled H<sub>2</sub>O for one week and had minimal dye diffusion. This indicates that the dye must be added prior to the freeze-thaw crosslinking method. | *Each of the samples had a very fast diffusion rate.
