Abstract
Therapeutic compositions, comprising: an anti-reactive oxygen species agent and a pervious polymersome, the pervious polymersome encapsulating the anti-reactive oxygen species agent, and the pervious polymersome having therein channels defined by a channel diblock copolymer, the channels being arranged so as to retain at least some of the anti-reactive oxygen species agent within the pervious polymersome while allowing reactive oxygen species to pass into the pervious polymersome. Method of treating a patient, comprising: administering an effective amount of a therapeutic composition, the therapeutic composition comprising an anti-reactive oxygen species agent disposed within a pervious polymersome, the pervious polymersome encapsulating the anti-reactive oxygen species agent, and the pervious polymersome having therein channels defined by a channel diblock copolymer, the channels being arranged so as to retain at least some of the anti-reactive oxygen species agent within the pervious polymersome while allowing reactive oxygen species to pass into the pervious polymersome.
