Problems solved by technology

[0003] At present, conventional drug carrier materials have the following disadvantages: poor targeting of cancer cells, unable to release in time at the lesion site; unstable structure, low drug loading capacity; poor biocompatibility; not suitable for industrial production, etc.
On the other hand, the single drug loading and single functionalization of the drug delivery system can no longer meet the treatment needs of complex diseases in the future

Abstract

The present invention proposes a gold nanorod-polymer composite injectable hydrogel, the gold nanorod-polymer composite injectable hydrogel is a block copolymer doped with drug-loaded nanoparticles and photothermal materials formed by reacting in an alkaline aqueous solution; the block copolymer comprises poly(3-methacrylamido dopamine- co ‑polyethylene glycol methyl ether methacrylate) and poly(vinylphenylboronic acid‑ co ‑polyethylene glycol methyl ether methacrylate). The hydrogel drug delivery system provided by the invention has the advantages of simple design, convenient operation and low cost, and is favorable for large-scale batch production.

Description

technical field [0001] The invention relates to a gold nanorod-polymer composite injectable hydrogel, a preparation method and application thereof, and belongs to the technical field of polymer biological materials. Background technique [0002] Since the 21st century, cancer has posed a huge threat to human health and life in both developed and developing countries. Currently, chemotherapy (chemotherapy) is one of the main methods used for cancer treatment worldwide. However, chemotherapy has disadvantages such as large cytotoxic side effects and low drug utilization rate. Therefore, researchers have carried out extensive research on drug carrier materials to overcome the shortcomings of traditional chemotherapy methods, reduce toxic side effects, and improve therapeutic effects. According to reports, Professor Jiao Tifeng's research group and Yan Xuehai's research group successfully prepared gold nanoparticles-collagen composite hydrogels through supramolecular self-assem...
