摘要：
Dual Microcapsules are disclosed. The outer membrane encapsulates a liquid having one or more smaller microcapsules (Mini-Microcapsules) suspended therein. The Mini-Microcapsules contain a conjugate or a reaction product of a Drug which diffuses into the liquid in which Mini-Microcapsules are suspended. The suspending liquid contains an enzyme which reacts with Drug complex or reaction product to regenerate or release the Drug. The drug diffuses through the outer membrane into a host.
