For this poly-m-aminophenol (PmAP), poly-o-aminophenol, and poly-p-aminophenol were electrochemically deposited from aqueous solution on the surface of glassy carbon (GC) electrode by potential cycling in the range of +0.2-+1.0 V. The modified GC electrodes were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, contact angle measurement and ellipsometry. It was found that poly-m-aminophenol modified GC electrode (PmAP/GC-electrode) is most suitable for electroanalytical determination of glutathione. An electroanalytical system for the determination of glutathione based on the PmAP/GC-electrode was developed. The analytical system was characterized by low limit of detection, good stability, high sensitivity and wide linear detection range.en10.1002/elan.201000584info:eu-repo/semantics/closedAccessElectrochemical polymerizationAminophenolGlassy carbonGlutathioneElectrochemical sensorsPolyanilineConducting polymersArticle233701709Q2WOS:000288093400019Q2
