Influence of electroactive interferents on glucose response at PPY/GOx/SWCNTs-PhSO3−/PB/Pt electrode
Interferent | Concentration (physiological normal, mM) | iGlu + interf/iGlua at E = 0 V |

aiGlu is the response current to 2 mM glucose; iGlu + interf is the response current to 2 mM glucose in presence of interferent at physiological normal concentration. Results are obtained at the operation potential of 0 V.
