| Objective: The research and progress of several common pH-sensitive biomedical materials in drug delivery were summarized in order to provide references for subsequent research and development of pHsensitive biomaterials in the future. Methods: Through literature review, the effective mechanism of four types of pH-sensitive biomaterials and their application in drug delivery were summarized. The challenges and research directions in clinical translation were discussed. Results and Conclusion: pH-sensitive biomedical materials can make the drug reach and act on the lesion sites according to the acidity and alkalinity of different tissues and organs in the body, thereby achieving therapeutic effect. But, there were still many problems in the research and development of the products, and the biggest challenge is how to select, modify and integrate the corresponding materials to design and produce safe and effective pH-sensitive biomedical materials. The technical problems caused by the different structural characteristics of biomaterials needed to be solved so as to realize the real productization and clinical application. |
