Figure 6. Mass transfer properties of empty microcapsules.

Figure 6

(a) The fluorescence intensity of FITC before and after outward diffusion. Empty microcapsules were incubated in a FITC solution (0.1 mg/mL) for 4 hours to achieve equilibrium of the fluorescence, and 100 μL of microcapsules containing FITC was then added to 900 μL of saline solution. The FITC inside the capsules immediately diffused outward and reached equilibrium. (b) The fluorescence intensity of FITC before and after inward diffusion. A 20-μL aliquot of empty microcapsules was added to 200 μL of FITC solution (10 μg/mL) and immediately photographed by CLSM. The FITC diffused inside the microcapsules and rapidly reached equilibrium. The experiments have been repeated for three times.
