In this work, a NiO–CNT nanocomposite and 2-(3,4-dihydroxyphenethyl)isoindoline-1,3-dione (DPID) were used as modifiers for the modification of a carbon paste electrode (DPID/NiO–CNT/CPE) for the electro-catalytic analysis of glutathione (GSH). The electro-catalytic interaction between DPID and GSH on the surface of the DPID/NiO–CNT/CPE was used as a new way for the analysis of GSH. GSH can be detected on the surface of the DPID/NiO–CNT/CPE in the concentration ranges of 0.03–10.0 and 10.0–200.0 μM with a detection limit of 0.015 μM. The DPID/NiO–CNT/CPE facilitated the simultaneous analysis of glutathione (GSH) in the presence of uric acid (UA) and tryptophan (Trp). The DPID/NiO–CNT/CPE showed high performance ability for GSH analysis in real samples.

电化学纳米结构平台，用于在尿酸和色氨酸存在下分析谷胱甘肽

在这项工作中，使用NiO-CNT纳米复合材料和2-（3,4-二羟基苯乙基）异吲哚啉-1,3-二酮（DPID）作为修饰剂，用于修饰碳糊电极（DPID / NiO-CNT / CPE）用于谷胱甘肽（GSH）的电催化分析。DPID / NiO-CNT / CPE表面上DPID和GSH之间的电催化相互作用被用作分析GSH的新方法。可以在0.03–10.0和10.0–200.0μM的浓度范围内在DPID / NiO–CNT / CPE的表面上检测到GSH，检测限为0.015μM。在存在尿酸（UA）和色氨酸（Trp）的情况下，DPID / NiO–CNT / CPE有助于同时分析谷胱甘肽（GSH）。DPID / NiO-CNT / CPE对真实样品中的GSH分析具有高性能。
