| titleOfInvention | A kind of biodegradable drug-loaded polymer material scaffold and preparation method thereof |
| abstract | The invention discloses a biodegradable drug-carrying polymer material stent and a preparation method thereof, belonging to the technical field of polymer materials. The biodegradable drug-loading polymer material stent of the present invention comprises the following raw materials: chitin, calcium phosphate, polyacrylic acid resin, vinylpyrrolidone, compound amino acid, chondroitin sulfate, and therapeutic drug; the preparation method is as follows: firstly prepare a The mesh structure stent is sprayed on the mesh structure stent after ultrasonic atomization, so as to obtain a biodegradable drug-loaded polymer material stent. The biodegradable drug-loaded polymer material scaffold of the present invention has a tensile strength of up to 72.5 MPa and a bending strength of up to 25 MPa, indicating that the mechanical properties are good; the in vitro cytotoxicity tests are all grade 1, indicating that the effect on cell activity is small. It has excellent cytocompatibility and has important application value. |
