Preparation and In Vitro Release of Drug-Loaded Microparticles for Oral Delivery Using Wholegrain Sorghum Kafirin Protein

Figure 1

Scanning electron micrograph of empty and prednisolone-loaded microparticles made using kafirin extracted from raw white grain, raw red grain, and cooked red grain. (A, B) empty and (C, D) prednisolone-loaded microparticles of kafirin from raw white grain; (E, F) empty and (G, H) prednisolone-loaded microparticles of kafirin from raw red grain; and (I, J) empty and (K, L) prednisolone-loaded microparticles of kafirin from cooked red grain. Scanning electron micrographs (A), (C), (E), (G), (I), and (K) were captured at 20,000x while (B), (D), (F), (H), (J), and (L) were captured at 50,000x magnification.
