The invention provides the preparation of antibacterial hemostatic porous microspheres with good biocompatibility, non-toxicity and biodegradability, which uses an inverse emulsion method to prepare sodium alginate/cellulose nanocrystalline porous microspheres. The preparation method of antibacterial and hemostatic porous microspheres of sodium alginate and nanocrystalline cellulose is simple, the materials are readily available, and the safety factor is good; the sodium alginate/cellulose nanocrystal-loaded ε-polylysine porous microspheres prepared by the method of the invention Microspheres are used for wound hemostasis, which can quickly absorb blood to reduce blood flow, promote the local accumulation of red blood cells, coagulation factors, platelets, etc. in the wound, thereby promoting hemostasis; in addition, due to its antibacterial properties, it can prevent wound infection and promote tissue healing. |
