Electrochemical determination of sulfamethoxazole in biological and drug samples using Ce (III)-doped CuO modified electrode

An electrochemical sensor for the determination of environmentally hazardous fungicide pyrimethanil in water and fruit samples

“…38 However, doping of metal oxides with various kinds of chemical agents may modulate their band gap, resulting in the introduction of new doping energy levels in the metal oxides and thus improving their electrocatalytic activity. 39 In recent years, the evolution of electrical devices doped with rare earth (RE) based on metal oxides has remained an interesting research eld due to its ability to be used in industry on a larger scale with lower production cost, using simple manufacturing technology, high thermal stability, and a high coefficient of incorporation for RE ions. 40 Moreover, due to the excellent properties of RE ion-doped metal oxides, these new materials are promising hosts for various applications, including lasers, light-emitting display devices, solar cells, energy converters, sensors and biosensors.…”
