Improving blood compatibility of surfaces using tanfloc and carboxymethyl-kappa-carrageenan polyelectrolyte multilayers
Blood-contacting medical devices are indispensable in modern medicine but often cause complications like thrombosis, infections, and undesirable cellular responses. This research addresses these challenges through surface modifications using bio-derived polymers and nanoscale topographies. The …

Surface modification of traditional and bioresorbable metallic implant materials for improved biocompatibility
… Little work has been done on determining the blood compatibility of these materials or on examining how their surfaces can be improved to improve cell adhesion, however. We examined thethrombogenic response of blood exposed to various resorbable ferrous stent materials through contact with …

Fabrication and characterization of a magnetic bacterial nanocellulose for neurovascular reconstruction of cerebral aneurysms
… contribute to deterioration and dilation of the blood vessel. A desirable treatment of cerebral aneurysms is the complete cut-off of the defect from the parent artery with minimum luminal obstruction. Even though different approaches have shown to exclude the defect from the parent artery, the …

Modifizierung von Membranoberflächen zur Verbesserung der Blutkompatibilität
Durch verschiedene Modifizierungen an der Blutkontaktseite von Hohlfasermembranen sollte eine Verbesserung der Bio- und Blutkompatibilität erreicht werden. Zur Modifizierung wurden verschiedene biologisch wirksame Moleküle verwendet. Weiterhin wurden zwei Modifizerungsstrategien verfolgt. Zum einen …
