Ratiometric fluorescence and mesoporous structure dual signal amplification for sensitive and selective detection of TNT based on MIP@QD fluorescence sensors†
Abstract
Molecularly imprinted polymer coated quantum dot (MIP@QD) fluorescence sensors combined with ratiometric fluorescence techniques and mesoporous silica materials have been applied to detect TNT for the first time. The assay platform exhibited excellent selectivity and sensitivity with a detection limit as low as 15 nM.
