Figure 7. Sustained insulin delivery.

Figure 7

A. Pictures of patches before (left) and 24 hours after powder insulin delivery (middle) as well as picture of blank patches (right). Experiments were repeated 3 times and representative pictures were shown. Scale: 667μm. B–C. Powder insulin-coated patches were topically applied onto AFL-treated skin of STZ-induced diabetic mice or extracted for s.c. injection. At different time points, serum insulin levels (B) and BGLs (C) were measured. Non-treated mice served as control. n=7–9.
