Emulsion Cross-Linking Technique for Human Fibroblast Encapsulation

Figure 1

Microencapsulation. Prepared microcapsules with (A) Tween 80 and (B) without surfactant. The emulsion or oil layer is seen in the upper white opaque area while the calcium chloride solution is the clearer area under the oil layer. The picture shows the effect on microcapsule morphology under microscope of (A1) 1% Tween 80, (A2) 2% Tween 80 (A3) 3% Tween 80, and (A4) 5% Tween 80.
