This research focuses on the development of a highly efficient electrocatalyst, CuO/NPC@CoO/NPC-10-7, for detecting glucose and ascorbic acid. In a 0.1 M NaOH solution, the modified electrode exhibits a sensitivity of 3314.29 μA mM cm for glucose detection. The linear range for ascorbic acid sensing is 0.5 μM - 23.332 mM, with a detection limit as low as 0.24 μM. In a 0.1 M PBS solution, the linear range for ascorbic acid detection extends to 43.328 mM, which represents the best performance reported to date by chronoamperometry. Moreover, the electrode demonstrates high accuracy, with a recovery rate of 96.80 % - 103.60 % for glucose detection and a recovery rate of 95.25 % - 104.83 % for ascorbic acid detection. These results suggest that the CuO/NPC@CoO/NPC-10-7 modified electrode shows significant potential for practical applications in food detection.
本研究专注于开发一种高效的电催化剂，CuO/NPC@CoO/NPC-10-7，用于检测葡萄糖和抗坏血酸。在 0.1 M NaOH 溶液中，修饰后的电极对葡萄糖检测的灵敏度为 3314.29 μA mM cm。对于抗坏血酸感应，线性范围为 0.5 μM - 23.332 mM，检测限低至 0.24 μM。在 0.1 M PBS 溶液中，抗坏血酸检测的线性范围扩展到 43.328 mM，这是目前通过计时安培法报道的最佳性能。此外，该电极表现出高准确性，葡萄糖检测的回收率为 96.80 % - 103.60 %，抗坏血酸检测的回收率为 95.25 % - 104.83 %。这些结果表明，CuO/NPC@CoO/NPC-10-7 修饰电极在食品检测的实际应用中具有很大的潜力。
