In the present study, a fluorescent probe based on aptamer gold nanoclusters (apt-AuNCs) was prepared for ultrasensitive detection of Hg 2+ in food.
Abstract Mercuric ion (Hg 2+ ) is a hazardous pollutant widely exist in living organisms, foods and environments with highly toxic bio-accumulative properties. In this work, fluorescent probe based on aptamer gold nanoclusters (apt-AuNCs) was prepared for ultrasensitive detection of Hg food. The fluorescence apt-AuNCs quenched the presence due to strong metallophilic interactions between 5d 10 centers Au + . Under optimal conditions, proposed displayed linear relationship concentration range...
