Abstract

The present disclosure discloses an integrated nano system for liver-targeting co-delivery of genes/drugs and a preparation method, belonging to the field of biomedicines. In the disclosure, a plurality of functions are integrated in a carrier having good biocompatibility and safety, a nucleic acid/drug-loading copolymer portion having a pH-stimulating response function is formed by poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) grafted with poly(3-azido-2-hydroxypropylmethacrylate) (PGMA-N3), and a fluorescence-based imaging component Rhodamine B (RhB) and galactose are used as targeting ligands. The drug delivery system provided by the present disclosure is safe, is capable of taking a synergistic effect of gene/drug therapy, and is expected to play a great role in clinical application.
