چکیده
Manual grinding of CuCl(2), 2,2'-bipyridine and hydrophobic CdSe QDs creates a selective and fast turn-on fluorescence sensor for detection of nanogram quantities of solid cyanide salts by the naked-eye. Using a fluorescence detector this simple sensor detects 100 ppm of NaCN in sand.

Selective turn-on fluorescence detection of cyanide in water using hydrophobic CdSe quantum dots.
The ability of 2,2'-bipyridine-bound copper(ii) ions to quench the photoluminescence of hydrophobic CdSe quantum dots is used to create a novel, selective turn-on fluorescence cyanide sensor.
متن کاملTurn-on fluorescent cyanide sensor based on copper ion-modified CdTe quantum dots.
A new fluorescent sensor for the sensitive and selective detection of cyanide (CN(-)) in aqueous media was developed herein. The sensing approach is based on CN(-)-modulated quenching behavior of Cu(2+) toward the photoluminescence (PL) of CdTe quantum dots (QDs). In the presence of CN(-), the PL of QDs that have been quenched by Cu(2+) was found to be efficiently recovered, which then allows t...
