The enzymatic degradation of the capsules in the presence of chitosanase was explored by scanning electron microscopy (SEM). With increasing time, the chitosan component was degraded by chitosanase, and the capsules began to deform and were finally destroyed. Sustained release of the encapsulated proteins was attained by using the enzymatic degradation of the hollow capsules. The release behavior was successfully manipulated by altering the charge of capsule surface.
