| titleOfInvention | Preparation method and application of pH-responsive controlled-release copper nano material |
| abstract | The invention relates to a copper-containing composite nano material with pH response and controllable release of copper ions, and a preparation method and application thereof. The composite nano material consists of magnesium hydroxide and copper hydroxide; the copper hydroxide is attached to the magnesium hydroxide. The preparation method comprises the following steps: adding the nano magnesium oxide particles into the solution containing copper ions, stirring and then shaking; centrifuging to separate solid from liquid; obtaining a solid; drying the obtained solid at the temperature lower than 50 ℃; obtaining the composite nano material. The application includes the application in the osteogenic antibacterial aspect. The nano material designed and prepared by the invention does not release copper ions in a neutral environment; copper ions are released in the cytosol and/or in the more acidic regions following infection. When the content of copper in the pH response controlled release copper nano material is 2.1-15.8wt.%, the material is suitable for promoting bone healing. The material has reasonable component and structural design, simple and controllable preparation process, and excellent performance of the obtained product, and is convenient for large-scale application. |
