The IR analyses proved that the polymerization effects really occurred. The BET adsorption test indicated that the adsorption amount of MIPMs to LMD was as three times as that of non-imprinted microspheres. The controlled release test indicated that the release ratio of LMD on NIPMs was linearly increased with increasing time, which suggests that the release process is completely controlled by diffusion. Meanwhile, the release ratio of LMD on MIPMs was curvedly increased with increasing time, which indicates that the release process is controlled by both diffusion and the imprinting effect.

药物扩散实验表明， LMD在非印迹微球上的释药率几乎与时间呈直线关系，说明其释药过程完全受扩散控制；而LMD在MIPMs上的释药率则呈曲线上升趋势，说明其释药过程除了受扩散控制外，还受到药物模板分子与MIPMs之间的印迹效应的协同作用的控制，从而达到了缓释药物分子的目的。
