硅藻纳米止血材料的研究进展

Research Progress of Diatom Nanomaterials for Hemostasis

传统的止血材料存在诸多局限性,而纳米材料具有优异的黏附性、多功能性及可设计性。介绍了硅藻介孔硅的材料学特性,综述了硅藻生物硅的止血应用。此类材料具有高度有序的孔隙结构,表面的硅醇基团带负电荷可加速血液凝固,成为优良的止血材料,在生物医学中具有广阔的应用前景。

There are many limitations in traditional hemostatic materials,but nanomaterials are characterized with excellent adhesion,versatility and designability.The study introduces the materials science of diatom mesoporous silica,and summarizes the hemostasis application of diatom biology silica.This kind of material has a highly ordered pore structure.The surface of the silanol group with negative charge can accelerate blood coagulation.So it becomes an excellent hemostatic material,and has a broad application prospect in biomedicine.
