Fig. 5 — Percent DOX absorbed to the hydrogels of varying formulations vs. time (a). In a few hours, most of the DOX in loading solution (50 μg/ml) was absorbed to the charged hydrogels. Gross picture of DOX absorbed to the hydrogels of varying formulations (b). Percent DOX loaded to the hydrogels from 1 ml loading solutions of varying concentrations (c). Amount of DOX loaded from 1 ml loading solution of varying concentrations normalized to the weight of hydrogel disks (d).
