An electrochemical sensor has been developed for the detection of Bisphenol-A (BPA) using photolithographically patterned platinum electrodes modified with multilayer graphene nanobelts (GNB). Compared to bare electrodes, the GNB modified electrode exhibited enhanced BPA oxidation current, due to the high effective surface area and high adsorption capacity of the GNB. The sensor showed a linear response over the concentration range from 0.5 μM-9 μM with a very low limit of detection = 37.33 nM. In addition, the sensor showed very good stability and reproducibility with good specificity, demonstrating that GNB is potentially a new material for the development of a practical BPA electrochemical sensor with application in both industrial and plastic industries.
电化学传感器已被开发用于检测双酚 A（BPA），使用光刻图案化的铂电极修饰多层石墨烯纳米带（GNB）。与裸电极相比，GNB 修饰电极由于 GNB 的高有效表面积和高吸附能力，表现出增强的 BPA 氧化电流。传感器在 0.5 μM-9 μM 的浓度范围内呈现线性响应，检测限非常低= 37.33 nM。此外，传感器表现出非常好的稳定性和重现性，具有良好的特异性，表明 GNB 是一种潜在的新型材料，可用于开发具有工业和塑料工业应用的实用 BPA 电化学传感器。
