Abstract

We report a facile route to synthesize size tunable Fe₃O₄ nanoparticles (NPs)–carbon nitride nanotube (CNNT) hybrids. These hybrids showing the water-soluble property are proven to exhibit ultra high peroxidase mimetic activity compared to those of pure NPs, where a colorless peroxidase substrate 3,3,5,5-tetramethylbenzidine changes by H₂O₂ to its blue colored oxidized state.
