Abstract
We developed a novel method for Cu(2+) detection based on the ion promoted oxidation reaction. Chemodosimeter L (weak fluorescence) can be oxidized into 3-benzothiazoly-7-N,N-diethylaminocoumarin (strong green fluorescence, coumarin 6) by Cu(2+) with high selectivity and sensitivity in HEPES (10 mM, pH = 7.4) buffer containing 50% (v/v) water-CH(3)CN solution.
摘要
我们开发了一种基于离子促进氧化反应的新型 Cu(2+)检测方法。化学传感器 L（弱荧光）在 HEPES（10 mM，pH = 7.4）缓冲液中，在含有 50%（v/v）水-CH(3)CN 溶液的条件下，可被 Cu(2+)高选择性和高灵敏度地氧化为 3-苯并噻唑-7-N，N-二乙氨基香豆素（强绿色荧光，香豆素 6）。
