WS2 nanotubes are functionalized with polymeric ligands by complexation with a combination of Ni2+ via a scorpionate-type nitrilotriacetic acid (NTA) ligand. The NTA group also allows the specific binding of proteins to the sidewalls of the tubes. The surface-bound protein retains its catalytic activity. This biofunctionalization of NT-WS2 opens new opportunities for integrating chalcogenide nanoparticles in (bio)composites.
