摘　　要：重金属污染是当下严峻的环境问题。传统的水体重金属检测方法存在操作复杂、慢速且高成本的问题,因此,开发一种简单高效、低成本的新型检测技术意义重大。本文以银离子作为检测对象,利用核酸适配体技术和聚集诱导发光(Aggregation-Induced Emission,AIE)技术,将特定的核酸适配体与具有聚集诱导发光效应的阳离子型AIE分子(四苯基乙烯衍生物TPEDPy2CH3I)结合,构建了一种针对水体中银离子浓度检测的新型复合探针体系。该检测方法具有高选择性、快速响应和低检测限等特点,同时也能够为水体中其他重金属离子的检测提供一定的参考和启发。Heavy metal pollution is a serious environmental problem today.Conventional methods for detecting heavy metals in water bodies are complicated,slow and costly.Therefore,it is of great significance to develop a new detection technique that is simple,efficient and low-cost.In this paper,a novel composite probe system for the detection of silver ion was constructed by combining a specific aptamer with a cationic molecule(tetraphenylethylene derivative TPEDPy2CH3I)bearing the features of Aggregation-Induced Emission(AIE).The method is characterized by high selectivity,fast response and low detection limit,which can also provide certain reference and inspiration for the detection of other heavy metal ions in water bodies.
