An n-gonal bipyramid or dipyramid is a polyhedron formed by joining an n-gonal pyramid and its mirror image base-to-base. An n-gonal bipyramid has 2n triangle faces, 3n edges, and 2 + n vertices. The referenced n-gon in the name of the bipyramids is not an external face but an internal one, existing on the primary symmetry plane which connects the two pyramid halves.
Preparation method and application of gold nanobipyramid@zif-8 wrapped curcumin co-loaded nano preparation
The application discloses a preparation method and application of gold nanometer bipyramid@ZIF-8 wrapped curcumin co-loaded nano-preparation, and comprises the following steps: S1, gold nanometer bipyramid is prepared and photoresponsive ligand modification is carried out; S2, the gold nanometer bipyramid is dispersed in a reaction system containing zinc salt, polyvalent metal salt, organic imidazole ligand, curcumin and defect inducer to form a mixed system; S3, double-wavelength near-infrared light irradiation is applied to induce in-situ growth of ZIF-8 layer doped with polyvalent metal ions on the surface, and a multi-level defect structure is formed; S4, a second active substance is loaded; S5, a biological enzyme responsive linker or an active targeting ligand is modified; and S6, a biological source polymer material is coated. Through synergistic regulation of photoinduced in-situ growth and defect engineering, the application realizes controllable growth and multi-level defect construction of the ZIF-8 layer, and the prepared nano-preparation is uniform in structure, closely combined in interface, stable in double active substance loading, excellent in enzyme-like catalytic activity, and can be used for preparation of tumor treatment drugs.
