Abstract
A wettable well was fabricated on an electrode, which was further modified with carbon quantum dot-scaffolded nanocomposites of melamine and copper for probing histidine through a unique displacement reaction route. The developed electrode with wettable well enables the condensing enrichment of analytes from the sample droplets, improving the electroanalytical sensitivity.
摘要
在电极上制备了一个可润湿的井，进一步用三聚氰胺和铜的碳量子点支架纳米复合材料修饰该电极，通过独特的置换反应途径来探测组氨酸。具有可润湿井的开发电极能够从样品液滴中浓缩富集分析物，提高了电分析灵敏度。
