In this work two phenol biosensors, one based on polyaniline nanofibers (PNFs) and the other based on the newly created and introduced linear-dendritic matrix of poly(citric acid)-block-poly(ethylene glycol) copolymers (PCA-PEG-PCA), were chemically modified with horseradish peroxidase (HRP) enzyme. These phenol biosensors showed an oxidation peak at 0.55V. The amperometric response for biosensors based on PNFs showed a linear response range from 2.5x10(6) to 2.5x10(5)mol/L, with a detection limit of 2.5 mu M phenol. Also, the amperometric response for a biosensor based on PCA-PEG-PCA showed a linear response range from 2.5x10(6) to 4x10(5)mol/L, with a detection limit of 1.5 mu M phenol.
