Gold nanorods-based FRET assay for ultrasensitive detection of Hg2+.
A fluorescence method for detecting mercury ion in a homogeneous medium is proposed with gold nanorods (GNRs) as a fluorescence quencher on the basis of the fluorescence resonance energy transfer (FRET). Under the optimum conditions, the method exhibits a dynamic response range from 10 pM to 5 nM with a detection limit of 2.4 pM.
