Acid and disulfide biodegradable cross-linkers have been employed to generate microgel star polymers, using RAFT-polymer arms. RAFT end-groups were then exploited to attach functional compounds via both thiol-ene and thiol-pyridyl disulfide exchange reactions.

Drug delivery vehicles that release one or more drugs, e.g., an opioid antagonist and/or an opioid, in response to changes in the chemistry of body fluids, specifically in response to changes in the partial pressure of CO
2
in the environment of the hydrogel are described. The drug delivery vehicles include hydrogels that swell or shrink in response to changes in the partial pressure of CO
2
in their environment, thus regulating release of an entrapped drug.
