To disclose their adsorptive characteristic, a series of studies of Chitosan adsorbing metal ions (Cu2+, Ag+) and Chitosan adsorbing DNA to prepare immuno-microspheres have been done by Atomic Force Microscopy (AFM).

• 为了能够揭示其吸附特性，探讨其在作为药物载体方面的应用价值，本文利用原子力显微镜(Atomic Force Microscope，AFM)主要对壳聚糖吸附金属离子(Cu~(2+)、Ag~+)的吸附性能和壳聚糖吸附包埋DNA制备免疫微球进行了系列探索研究。
