The catalytic activity of ACC-α-Fe 2 O 3 allowing the detection of dopamine (DA) is systematically investigated. The results showed that the ACC-α-Fe 2 O 3 electrode exhibits impressive electrochemical sensitivity, stability and selectivity for the detection of DA. The detection limit determined with the amperometric method appears to be around 50 nM with a linear range of 0.074–113 μM. The impressive DA sensing ability of the as prepared ACC-α-Fe 2 O 3 electrode is due to the good electrochemical behavior and high electroactive surface area (19.96 cm 2 ) of α-Fe 2 O 3 nanoparticles anchored on the highly conductive ACC. It is worth noting that such remarkable sensing properties can be maintained even when the electrode is in a folded configuration. © 2017 Elsevier B.V.-Fe 2 O 3;Amperometry;Biosensor;Carbon cloth;Dopamine;Flexible;Wearable;α[SDGs]SDG3Amines;Biosensors;Carbon;Catalyst activity;Hematite;Nanoparticles;Neurophysiology;Wearable sensors;-Fe2O3;Amperometry;Carbon cloths;Dopamine;Flexible;Wearable;Electrochemical electrodesFlexible sensor for dopamine detection fabricated by the direct growth of α-Fe 2 O 3 nanoparticles on carbon clothjournal article10.1016/j.apsusc.2017.08.1682-s2.0-85028965314
