  • Temperature sensitive hydrogel composition including nucleic acid and chitosan
    Patent number: 11672756
    Abstract: The present invention provides a temperature sensitive hydrogel composition including a nucleic acid and chitosan. Since the hydrogel has excellent biocompatibility and biostability, and simultaneously has sol-gel phase transition properties depending on temperature changes, the hydrogel is present in a sol state at room temperature and becomes a gel when the hydrogel is injected into the human body or applied on the surface of epithelial skin and the temperature increases. Thus, the temperature-sensitive hydrogel of the present invention can be directly injected into and applied on certain parts requiring treatment and the retention and attaching time of a drug is increased through gelation depending on the temperature so that drug efficacy is sufficiently exhibited. Therefore, it is expected that the temperature-sensitive hydrogel of the present invention can be utilized for various treatments.
