SWNTs possess intrinsic peroxidase-like activity, catalyzing the reaction of peroxidase substrate 3,3,5,5-tetramethylbenzidene (TMB) in the presence of H2O2 to produce a color reaction. Here SWNTs have been used for label-free colorimetric detection of disease-associated single-nucleotide polymorphism with a direct detection limit of 1 nM.
