摘要汞离子(Hg²⁺)是一种致癌和无法生物降解的高毒重金属污染物,因此开发Hg²⁺的快速检测方法对环境监测和人类健康维护具有重要意义。本研究成功构建了对Hg²⁺快速裸眼筛查和检测的比率荧光传感器。首先采用水热合成法制备了发红色荧光的金纳米簇(Gold nanoclusters,AuNCs),采用微波辅助法制备了具有高量子产率(85%)且发蓝色荧光的碳量子点(Carbon quantum dots,CDs),然后将AuNCs和CDs简单混合,构建了具有单一激发和双发射的AuNCs-CDs比率荧光传感器。基于Hg²⁺和Au⁺的高亲和嗜金属效应,Hg²⁺可明显猝灭AuNCs-CDs中AuNCs在670 nm处的荧光发射峰,而CDs在420 nm处的参比荧光强度基本保持不变。AuNCs-CDs的比率荧光信号(I₆₇₀/I₄₂₀)与在0.005～1 mg·L^-1范围内的Hg²⁺浓度呈良好的线性关系,检出限为1.5 μg·L^-1。与此同时,随着Hg²⁺浓度的增加,AuNCs-CDs在紫外灯下的发光颜色可用裸眼明显分辨(由粉红色变为蓝色)。该方法不仅对其他金属离子具有抗干扰性,而且在河水、大米以及白菜实际样品检测中也具有可行性,加标回收率为84.5%～105.1%。因此,利用AuNCs-CDs可构建一种理想的比率荧光传感器,其可用于Hg²⁺的快速灵敏检测,并有望真正应用到食品安全和环境检测中。

Abstract: Mercury ion (Hg²⁺) is a contaminant of strong carcinogenicity, non-biodegradability and hypertoxicity, thus it is significant to design a rapid detection method of Hg²⁺ to protect the human health and earth environment. In this work, a radiometric fluorescence sensor, via a single excitation wavelength and dual emission wavelength, was developed by mixing gold nanoclusters (AuNCs) and carbon quantum dots (CDs) for rapid naked-eye screening and detection of Hg²⁺, where the AuNCs with red fluorescence were prepared by hydrothermal synthesis method, and the CDs with blue fluorescence were prepared by microwave-assistant method with high quantum yield (85%). Based on the high-affinity metallophilic Hg²⁺-Au⁺ interactions, the fluorescence emission peak of AuNCs at 670 nm could be quenched significantly, while the reference fluorescence intensity of CDs at 420 nm was basically not affected by Hg²⁺in AuNCs-CDs. There is a linear relationship between the ratiometric fluorescence signal (I₆₇₀/I₄₂₀) of AuNCs-CDs and the concentration of Hg²⁺ (0.005—1 mg·L^-1) with the limit of detection of 1.5 μg·L^-1. As the concentration of Hg²⁺ rising, the fluorescence color of AuNCs-CDs could be distinguished by bare-eyes (from pink to blue) under UV lights. This developed method was not only anti-interferential to other metal ions, but also feasible in the detection of actual samples, such as river water, rice and cabbage, with the recovery rate of Hg²⁺ in the range of 84.5%—105.1%. Therefore, AuNCs-CDs can be used to construct an ideal ratiometric fluorescent sensor for the rapid and sensitive detection of Hg²⁺ to the further applications on the food safety and environmental detection.

Key words: gold nanoclusters (AuNCs) carbon quantum dots (CDs) ratiometric fluorescence sensor rapid detection mercury ion (Hg²⁺)
