Table 1.
The abbreviations, composition, and geometry of all of the hydrogel samples used in this study. The abbreviations for the groups are meant to emphasize the differences in composition and structure that are being investigated in each experiment. The numbers in bold indicate where the parameters have been changed in each grouping.
