Figure 4. Sustained powder SRB delivery in gelatin skin.

Figure 4

Powder SRB-coated 4×4 array patches were topically applied onto AFL-treated or intact gelatin skin. At different times, topical view of the delivery (A) and images of patch MCCs (B) were taken by a digital camera. Enlarged pictures of patch MCCs were shown in lower panels of B. Blue arrow points to signs of water infiltration at 0.5 hour or MCCs with clear color change at later time points.
