Advances in anti-thrombogenetic strategies of biomaterials
The presence of thrombus on the surface of blood-contacting biomaterials in clinical practice can significantly impact both the longevity of the biomaterials and the overall survival prognosis of patients.The administration of anticoagulant and antiplatelet medications may heighten the risk of systemic bleeding.Developing biomaterials with anti-thrombogenetic properties and enabling localized anti-thrombosis may offer a solution to these challenges.The development strategies for anti-thrombogenetic biomaterials can be categorized into three main approaches based on the mechanisms of thrombus formation on biomaterial surfaces:altering physical and chemical properties,designing coatings containing or releasing active substances,and promoting endothelialization.However,due to the intricate and interconnected nature of these mechanisms,biomaterials constructed using a single approach may not effectively prevent thrombus formation.The collaborative intervention of various mechanisms can facilitate the development of biomaterials with enhanced blood compatibility.
