The composites of IL (BmimBF 4 ) and various nitrogen doped carbon nanotubes (NCNTs) synthesized by post treatment under NH 3 at different temperatures have been explored as a novel composite material for the sensitive and selective detection of dopamine (DA). The electrocatalytic activity of these various NCNTs‐IL composites for the detection of DA was examined by voltammetric and rotating disc electrode (RDE) measurements. These novel NCNTs‐IL composites exhibit a superior sensitivity and selectivity towards the oxidation of DA in presence of higher concentration of AA (500 µM). A linear response between the peak current and the concentration of DA was found to be in the concentration range of 0.001 µM–40 µM and 0.001 µM–10 µM for individual and even in presence of 500 µM of AA respectively.
