| titleOfInvention | Biodegradable mesoporous nano magnetic material and preparation method thereof |
| abstract | The invention provides a biodegradable mesoporous nano magnetic material and a preparation method thereof. The method comprises the steps of dissolving a certain amount of calcium, phosphate and carbonate salt in an aqueous solution by adopting an in-situ coprecipitation method, stirring at a constant temperature at a certain temperature, adding a certain amount of soluble salts such as iron, cobalt and nickel, continuously stirring at a constant temperature for 10s-120h, filtering a product, washing with ethanol for 2 times, drying in air, calcining at the temperature of 600 ℃ and 1200 ℃ for 2-12h, placing the product in a citric acid-sodium hydroxide buffer solution with the pH of 4.5-7.4, continuously stirring at a certain temperature for 30min-24h, washing with deionized water for 2 times, washing with ethanol for 2 times, and drying at the temperature of 50-60 ℃ to obtain the nano mesoporous magnetic material with the skeleton containing the nano magnetic material. The mesoporous nano magnetic material synthesized by the method can be used as a magnetic targeting material for directional killing of tumor and cancer tissues, has biodegradability, can be gradually degraded and discharged in a living body, and avoids accumulation and enrichment of nano particles in the living body. |
