Abstract
A polymeric delivery system delivers a biologic to cells. In some embodiments, the polymeric delivery system includes polyplexes. Each polyplex includes at least one charged polymer and at least one biologic. The at least one charged polymer includes a polyester copolymer of a polyol and a polycarboxylic acid modified with at least one charged moiety having an opposite charge from a net charge of the at least one biologic. In other embodiments, the polymeric delivery system includes self-assembled particles including a block copolymer and a biologic associated with the block copolymer. The block copolymer includes a first block of a polyester copolymer of a polyol and a polycarboxylic acid and a second block of a second monomer or a second polymer.
