    摘要: Nucleotide delivery polymers, compositions, and associated methods for the enhancement of gene delivery and expression in solid tissues are provided. In one aspect, for example, a nucleotide delivery polymer may include a poloxamer backbone having a metal chelator covalently coupled to at least one terminal end of the poloxamer backbone. In another aspect, the nucleotide expression polymer has a metal chelator coupled to at least two terminal ends of the poloxamer backbone.

    摘要: A biodegradable cross-linked cationic multi-block copolymer of linear polyethylenimine (LPEI) wherein the LPEI blocks are linked together by hydrophilic linkers with a biodegradable disulfide bond and methods of making thereof. The biodegradable cross-linked cationic multi-block copolymer may also contain pendant functional moieties which are preferably receptor ligands, membrane permeating agents, endosomolytic agents, nuclear localization sequences, pH sensitive endosomolytic peptides, chromogenic or fluorescent dyes.
