Abstract: Polymeric carriers for the delivery of therapeutic agents and methods for making and using the same. The polymeric carriers include copolymers, diblock copolymers, polymeric architectures that include the copolymers and diblock copolymers, and particles assemblies comprising the copolymers, diblock copolymers, and polymeric architectures that include the copolymers.

Abstract: Polymeric compounds having spatially controlled bioconjugation sites are described. Functionalization is achieved by selective ?-terminal chain extension of polymer chains by radical polymerization, such as reversible addition-fragmentation chain transfer (RAFT) polymerization.

Abstract: Described herein are copolymers, and methods of making and utilizing such copolymers. Such copolymers have at least two blocks: a first block that has at least one unit that is hydrophilic at physiologic pH, and a second block that has hydrophobic groups. This second block further has at least one unit with a group that is anionic at about physiologic pH. The described copolymers are disruptive of a cellular membrane, including an extracellular membrane, an intracellular membrane, a vesicle, an organelle, an endosome, a liposome, or a red blood cell. Preferably, in certain instances, the copolymer disrupts the membrane and enters the intracellular environment. In specific examples, the copolymer is endosomolytic.

Abstract: A composition for delivering an agent to a cell, comprising a bispecific affinity reagent and a pH-responsive, membrane destabilizing polymer. The bispecific affinity reagent may include a first affinity reagent covalently linked to a second affinity reagent, wherein the first affinity reagent binds to a molecule on the surface of a cell, and the second affinity reagent binds to an intracellular target.
