Abstract: The present invention discloses biodegradable glass based on an amino acid, a peptide and a derivative, as well as the preparation method and use thereof. The main raw material of the glass is one or more of an amino acid, a peptide, a derivative or salt thereof. Compared with traditional glass, the glass of the present invention has significant advantages such as high biocompatibility, biodegradability, being 3D printable, and being compostable, etc., and its preparation process is simple and green, which can effectively avoid the influence of the traditional glass on the ecological environment. The glass of the present invention has a wide range of applications in the fields such as medicine, building material, chemical industry, food, electronics, national defense, etc., including but not limited to tissue engineering, tooth/bone repair, drug sustained-release, cell/protein sequestration, optical fiber communication, coatings, precision instruments, etc.

Abstract: The present disclosure relates to an immunologically active peptide-biliverdin conjugate (I), a preparation method therefor and an application thereof in cancer diagnosis, and/or tumor immunotherapy, and/or tumor “photothermal immunotherapy” (tumor photothermal therapy combined with immunotherapy). The conjugate to which the present disclosure relates not only may stimulate an organism to generate a tumor-immune effect, but also may relieve and/or eliminate tumor inflammation, remodel a tumor inflammatory microenvironment and achieve photothermal cancer immunodiagnosis and immunotherapy. The conjugate to which the present disclosure relates has high biocompatibility, good stability and an extended half-life. The conjugate is prepared from an immunologically active peptide and biliverdin by means of chemical synthesis.
