HA‐coated CNTs are very stable in aqueous solution and are able to transport through porous media to a significant extent, indicating high environmental mobility. Use of magnetic metaloxide nanoparticles as affinity probes provides a permanent and efficient removal strategy for HA‐coated CNTs from aqueous media (see image).
