In this study, we found that glucose enhance electrochemiluminescence (ECL) intensity of both Au nanoclusters (Au NCs) and carbon quantum dots (CQDs) with K2S2O8 as the co‐reactants. The enhancing effects by Au NCs and CQDs were overlapped, enabling the detection of glucose. The increased ECL intensity of glucose was linear with the logarithm of concentrations of glucose in the range of 50 μM–3.0 mM, and the limit of detection is 20 μM. Anti‐interruption ability was achieved, and ascorbic acid, urea, and uric acid had little influence to glucose detection. This method realized the direct detection of glucose by enhancing ECL of Au NCs and CQDs, which was fast and economic, possessing potential applications for glucose detection in human serum.

碳量子点和金纳米簇对阴极ECL和葡萄糖非酶检测的协同增强作用
在这项研究中，我们发现葡萄糖可增强以K 2 S 2 O 8为共反应物的Au纳米团簇（Au NCs）和碳量子点（CQDs）的电化学发光强度。Au NCs和CQDs的增强作用重叠，可以检测葡萄糖。葡萄糖的ECL强度增加与葡萄糖浓度在50 μM–3.0 mM范围内的对数呈线性关系，检出限为20μM。达到了抗干扰能力，抗坏血酸，尿素和尿酸对葡萄糖的检测影响很小。该方法通过增强Au NCs和CQDs的ECL实现了葡萄糖的直接检测，快速，经济，在人血清葡萄糖检测中具有潜在的应用前景。
