摘要：

Two different strategies for developing new electrocatalytic platforms based on the modification of gold or carbon screen-printed electrodes with multiwall carbon nanotubes (MWCNTs) by diazonium salt click chemistry are described. The strategies proposed are compared to MWCNTs direct adsorption. The resulting platforms were characterized by scanning electronic microscopy (SEM), atomic force microscopy(AFM) and cyclic voltammetry (CV). It was observed that the strategies based on the diazonium chemistry give rise to a more ordered and homogeneous surface. The new sensing platforms exhibit electrocatalytic activity towards the NADH and hydrazine oxidation. Modification of these platforms with N,N-bis(3,4-dihydroxybenzylidene)-1,2-diaminobenzene (3,4-DHS) causes a decrease in the overvoltage of the NADH and hydrazine oxidation. Therefore, they have been applied as NADH and hydrazine sensors. (C) 2015 Elsevier B.V. All rights reserved.
