This invention provides particles encapsulating active agent that do not produce functional effects or remove functional effects until they are triggered by contacting with at least one exogenous source. The particles in this invention minimize toxic effects to the body of the active agent and the material that interacts with an exogenous source as well as minimize body chemicals from degrading both the active agent and the material that interacts with an exogenous source inside the particle.
