Preparation and physico-biochemical characterization of (Fe, Co, Ni) oxide nanoparticles-decorated PANI-MWCNTs as peroxidase mimetics

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 peroxidaselike 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 H2O2 reagent.
