The ITO based electrode utilizes a dense layer of 2D CuO nanostructures as an effective electron-transfer facilitator which promotes the electro-catalytic sensing of Sudan I in aqueous solution. The in-situ growth of CuO nanostructures was achieved using simple hydrothermal route with the assistance of tartaric acid utilized as an effective template. The in-situ grown layer comprises of 2D CuO nanostructures with morphological features similar to flowers composed of sharp-flake like features. The electro-catalytic oxidation of Sudan I over the described electrode system demonstrated low-over potential value and excellent working stability with good analytical linearity in the range of 0.001-1.56 mu M. The ITO based electrode was found highly selective and sensitive towards Sudan I with limit of detection determined to be 1.2 x 10(-4) mu M (S/N = 3).en10.1016/j.mssp.2017.12.001info:eu-repo/semantics/closedAccessCuOTartaric acidSudan IITO substrateArticle75296300Q1WOS:000424934600039Q2
