| Abstract |
Triacetone triperoxide (TATP), one of the most dangerous primary explosives, has emerged as an explosive of choice for terrorists in recent years. A new strategy for the detection of TATP is developed by utilizing amphiphilic polythiophene-coated CdTe QDs (P1QDs) and Hg2+ ion. The emission of P1QDs is found to be quenched in the presence of Hg2+ ion by electron transfer. Upon addition of the TATP, the quencher (Hg2+ ion) has been removed from the surface of P1QDs owing to the strong interactions between TATP and metal ions (Hg2+ ion), which leads to significant fluorescence recovery of P1QDs. The detection limit for TATP is 87 µg/L. The simultaneous possession of high sensitivity and selectivity could enable this sensor to be potentially applicable for ultrasensitive and rapid detection trace of TATP in real samples.
