The invention discloses highly branched poly (beta-amino ester), a preparation method thereof and application of the highly branched poly (beta-amino ester) in functional DNA delivery, and belongs to the technical field of biomedical materials. The functional highly-branched poly (beta-amino ester) is prepared by taking a micromolecular amine monomer, an acrylate monomer and branched micromolecular organic amine as raw materials and adopting a one-pot method, and the method is simple and efficient in synthesis and suitable for industrial large-scale production. The composite nanoparticles formed by highly branched poly (beta-amino ester) and COL7A1DNA are relatively uniform in distribution, good in stability, biodegradable and good in biocompatibility, and through C7 protein related skin cell and immunodeficient mouse in-vivo experiments, the composite nanoparticles have a good application prospect. The application potential of the highly branched poly (beta-amino ester) in the aspects ...
