摘要：
Embodiments of the disclosure may include a pressure sensitive hydrogel composition. The composition may include a liquid solvent, a polymer, and an acid gas. The composition may be capable of having a fluid phase in which the acid gas is dissolved in the solvent and the polymer is dissolved in the solvent, and the composition may be capable of having a gel phase in which the acid gas is not dissolved in the liquid solvent and the polymer is precipitated out of the solvent. The composition may also include a chemical compound or a pharmaceutical agent that can be released after the composition is delivered to a target tissue region.本發明揭露一種壓力敏感性水膠。壓力敏感性水膠組成包含溶劑、高分子還有酸性氣體。此組成可為液相,當其中酸性氣體溶於溶劑中,且高分子溶於溶劑中。此組成可為膠體,其中酸性氣體未溶於溶劑中且高分子由溶劑中析出。壓力敏感性水膠更包含化學化合物或是藥劑,其可以在壓力敏感性水膠設置至組織的標靶區域之後釋放出來。
