Carbon porous materials (CPMs) with high surface areas up to 2660 m(2) g(-1), directly fabricated by a facile microwave-assisted route, were applied to the electrochemical detection of dopamine (DA). The CPM-modified electrodes exhibited excellent selectivity, a desirable detection limit (2.9 nM), and extraordinary sensitivity (2.56 mA μM(-1) cm(-2)) for detection of DA, even in the presence of large amounts of foreign species, such as ascorbic acid (AA) and uric acid (UA), making feasible the practical applications of these electrodes as DA sensors.
通过简便的微波辅助路线直接制备的比表面积高达2660 m² g⁻¹的碳多孔材料(CPMs)被应用于多巴胺(DA)的电化学检测。即使在存在大量外来物质(如抗坏血酸(AA)和尿酸(UA))的情况下,CPM修饰电极对DA的检测仍表现出优异的选择性、理想的检测限(2.9 nM)和非凡的灵敏度(2.56 mA μM⁻¹ cm⁻²),使得这些电极作为DA传感器的实际应用成为可能。
