Covalent Binding of Dexamethasone to Polyimide Improves Biocompatibility of Neural Implantable Devices

Advanced Healthcare Materials, EarlyView.
The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.
