| titleOfInvention | Hydrogel blood vessel micro-stent and preparation method thereof |
| abstract | The invention provides a hydrogel blood vessel micro-stent and a preparation method thereof, wherein the preparation method comprises the following steps: a) 3D printing is carried out on the mixed solution of GelMA hydrogel and a photoinitiator to obtain a GelMA hydrogel sheet; b) carrying out self-curling of the simulated apple peel on the GelMA hydrogel sheet obtained in the step a) to obtain the hydrogel blood vessel micro-stent. Compared with the prior art, the preparation method provided by the invention constructs the hydrogel blood vessel micro-stent in an apple peel-imitated self-curling manner, is different from the traditional 3D printing method, can construct a finer micro hollow tube (below 200 mu m), can construct gel sheets with different shapes and sizes firstly, and then obtains a gel tube with a corresponding form, and has higher precision and controllability; in addition, the hydrogel blood vessel micro-scaffold prepared by the preparation method provided by the invention has good cell affinity, good biocompatibility and rich forms, can basically meet the bionic requirements of all forms of blood vessel scaffolds, and has huge development prospects. |
