| titleOfInvention | Preparation process of carbon-coated magnetic guiding drug carrier |
| abstract | The invention discloses a preparation process of a carbon-coated magnetic guiding drug carrier, belonging to an interventional therapy carrier and being characterized in that: NaOH, FeCl 3 ·6H 2 O、FeCl 2 ·4H 2 The molar ratio of O is OH ‑ ：Fe 3+ ：Fe 2+ 8.0: 1.0-1.8: 1.0, firstly, adding pregelatinized starch into a sodium hydroxide solution, and stirring until the pregelatinized starch is completely dissolved; and ultrasonically mixing the mixture at the frequency of 200Hz, then dropwise adding a mixed iron solution into the gelatinized mixed solution, reacting the mixture in a high-temperature reaction kettle under an inert atmosphere, keeping the temperature at 180-240 ℃ for 6-10 hours, naturally cooling, washing and drying to obtain the carbon-coated ferroferric oxide. Compared with the prior art, the invention overcomes the defects of complex coating process, high production cost, unstable product performance and the like of the traditional magnetic particle carrier for targeted therapy. |
