The electrochemical response of the f-MWCNTs/poly(ALR-S)/GCE towards SSY was examined by cyclic voltammetry (CV) and square wave voltammetry (SWV). Both recorded cyclic voltammograms (CVs) and square wave voltammograms (SWVs) showed that the oxidation/reduction peaks of SSY at f-MWCNTs/poly(ALR-S)/GCE were found to be much higher than the bare GCE, f-MWCNTs/GCE, and poly(ALR-S)/GCE. Calibration curves obtained from the SWVs indicated that the f-MWCNTs/poly(ALR-S)/GCE offers a linear response in the range of 0.50 to 256 mu M with a low detection limit (LOD) of 0.16 mu M and the sensitivity was found to be 9686 mu A mM(-1) cm(-2). The f-MWCNTs/poly(ALR-S)/GCE provides excellent performance for the detection of SSY in daily life samples with high accuracy and precision.eninfo:eu-repo/semantics/closedAccessSunset YellowAlizarin Red Sfunctionalized MWCNTsVoltammetry ElectrochemistryArticle34101644165510.1002/elan.202100566Q2WOS:0007825214000012-s2.0-85128173027Q2
