The active agent forms a noncovalently bonded inclusion complex within the cavity of I and thus remains assocd. with I and the coupled biorecognition mol. and thus can be delivered to the other half of the biospecific recognition.

• 活性剂在(I)的空腔内形成一个非共价键结合的包容络合物,因此保持了与(I)及被偶合的生物可识别分子的结合,因而能被投递到另一半生物可识别的分子上。
