ADENOSINE TRIPHOSPHATE INTERCALATED HYDROTALCITE FILM AND PREPARATION METHOD THEREFOR

摘要

The invention belongs to the technical field of biological-inorganic composites, and discloses an adenosine triphosphate (ATP) intercalated hydrotalcite film grown perpendicular to a substrate and a preparation method therefor. The invention uses an in-situ growth method to produce a hydrotalcite film to which ATP is then added. The specific steps are: first, forming an anodic aluminium oxide layer on the surface of a metallic aluminium, then producing a hydrotalcite film; next, immersing the hydrotalcite film into an ATP solution and drying it at room temperature to obtain an ATP intercalated hydrotalcite film. The advantages of the invention are that ATP is intercalated into the interlayer of hydrotalcite by applying an in-situ growth technique; this immobilizes the ATP, and achieves the slow release of target medicine by utilizing the interlayer confinement effect of hydrotalcite.
