ALG微胶囊为亲水性凝胶，其作为药物载体，包裹水溶性小分子药物，常发生泄漏，造成药物包封率较低，释放时间过短。
ALG microcapsule is a hydrophilic gel, as a drug carrier, it is easily leaked out encapsulated hydrophilic small molecular drugs, and cause a low encapsulate rate and a short releasing time.
方法：1、采用静电液滴法制备微胶囊，并选用不同分子量的壳聚糖，在不同成膜时间下制备不同的ACA微胶囊。
Methods: 1. Electrostatic droplet technique was adopted to fabricate ACA microcapsules with chitosan of different molecular weights and in different membrane-forming time.
