摘要：
Fluorescence nanoclusters have been used for the determination of melamine for the first time. The method is based on the fluorescence turn-on of oligonucleotide-stabilized silver nanoclusters (DNA-Ag NCs) by melamine. The enhancement factors (I-I-0)/I-0 increase linearly with melamine concentrations over the range 5.0 x 10(-8)-7.0 x 10(-6) M (R-2=0.99. The detection limit is 1.0 x 10(-8) M, which is approximately 2000 times lower than the US Food and Drug Administration estimated melamine safety limit of 20.0 mu M. Furthermore, the milk samples spiked with melamine are analyzed with excellent recoveries. (C) 2012 Elsevier B.V. All rights reserved.
