Endothelial membrane mimetic coating modified dialyzer for hemocompatible and anticoagulant-free hemodialysis

Poly(sulfobetaine) versus poly(ethylene glycol) based copolymer modified polyurethane catheters for antifouling

“…This hydration layer effectively prevents the interaction between the material and biomolecules, thereby enhancing its biocompatibility. 15,19–22 Zwitterions commonly used for surface modification include phosphorylcholine (PC), sulfobetaine (SB), and carboxybetaine (CB). Various methods, such as surface grafting, 23–26 dip-coating, 27 spin-coating, 28,29 spray-coating, 30 and solvent casting 31 can be employed to modify a surface using zwitterionic polymers.…”
