摘要:
Photoactivatable prepolymers and methods of use thereof are disclosed for microencapsulation of a substantially water-insoluble material within a nonporous shell. As provided herein, the microencapsulated material is released with no more than a slow release rate. Upon exposure of the nonporous shell to light, the nonporous shell is converted into a porous shell having an increased release rate for the microencapsulated material.
