Engineered Heparinized GQDS/HPEI–Polyamide Membrane for Bilirubin Removal via One Step Anti Coagulation

open access: yesAdvanced Materials Interfaces, EarlyView.
A multifunctional heparinized polyamide membrane embedded with graphene quantum dots (GQDs) and hyperbranched polyethyleneimine (HPEI) is engineered for efficient bilirubin removal via a one‐step anticoagulation–adsorption process. The membrane demonstrates enhanced hemocompatibility, prolonged clotting times, and high bilirubin adsorption capacity ...
