The diffusion way and speed of fluorescein into the microcapsulations were observed by confocal laser scanning microscopy. The comparison of fluorescein intensity was made in APA microcapsulations with different diameters.

• 共聚焦显微镜下观察葡聚糖荧光素在apa微囊中的扩散速度和扩散方式,并对比相同时间、不同直径的apa微囊中葡聚糖荧光素的强度,综合分析确定最佳的微囊直径。
