Genipin Cross-Linked Polymeric Alginate-Chitosan Microcapsules for Oral Delivery: In-Vitro Analysis

Figure 8

Analysis of fluorescence intensity inside and outside the microcapsule incubated in the solution of a fluorescent marker (20 KD FITC-dextran, 0.5 mg/mL). Peak 1 and Peak 2 in the intensity profile correspond to the fluorescence intensity inside (square 1) and outside (square 2) the microcapsule outlined in the insert, respectively.
