Figure 5. Halofuginone-loading in and release from silk films.

Silk films were loaded with Halofuginone via adsorption from solution method as described in the methods section. (A) The resulting Halofuginone loading masses were 6 ± 0.7 μg (low), 13 ± 0.4 μg (middle), 25 ± 1.3 μg (high). (B) Halofuginone release in PBS was monitored via UV spectroscopy (314 nm). All of the Halofuginone release from the low and middle loading groups, and 86% of the Halofuginone release from the high group.
