Description
Summary:In this research, a novel multiwall carbon nanotube/polyaniline (PANI-MWCNTs)-based metal oxides nanocomplex as a peroxidase mimetic was fabricated and characterized. Finally the peroxidase-like catalytic activity of nanocatalyst was investigated with the oxidation of peroxidase substrates: 4-aminoantipyrine (4-AAP)/phenol system and 3,3′,5,5′-tetramethylbenzidine (TMB) substrate in the presence of H 2 O 2 reagent. A nanocomposite of multiwalled carbon nanotubes/polyaniline and magnetic metal oxide nanoparticles can be used to catalyze the oxidation of peroxidase substrates.
