| Objective: To summarize the research progress of thermo-sensitive biomaterials in recent years in order to provide references for further research of subsequent thermo-sensitive biomaterials. Methods: The composition and principles of several commonly used thermo-sensitive materials were summarized through literature review, and their application in drug delivery was also introduced in this paper. Results: Thermosensitive biomaterials have good biocompatibility and low cytotoxicity. Chitosan or poly (N-isopropylacrylamide) (PNIPAM), as representative materials, can be used to control drug release because of thermosensitivity. Besides, they can improve the targeting. Conclusion: The volume of thermo-sensitive materials may change under the influence of environmental factors, and this property makes it a prosperous candidate for drug controlled release. Designing thermo-sensitive materials with excellent properties and applying them in clinic successfully will be one of the future research directions. |
