Tellurium-containing polymer coating with glutathione peroxidase mimics capability for surface modification of intravascular implants

•A novel tellurium-functionalized polycarbonate-polyurethane is designed and synthesized by introducing ditelluride bonds.•The tellurium-functionalized coating with glutathione peroxidase mimics capability can continuously and controllably catalyze the nitric oxide release.•The tellurium-functionalized coating is not only beneficial for quickly building health endodermis, but also effective in inhibiting blood coagulation, endometrial hyperplasia and inflammation.
