摘要：
The invention provides a method to release drugs from a polymer matrix upon demand without degrading the matrix. By applying ultrasound to a self-healable polymer matrix in physiological environment, compounds of both low-molecular and high-molecular weights encapsulated in the matrix are delivered at controlled rates, while the integrity and stiffness of the matrix are unaffected.
