Abstract:
We demonstrate for the first time that bifunctional Au-Fe(3)O(4) dumbbell nanoparticles can be used for sensitive and selective turn-on fluorescent detection of cyanide based on the inner filter effect, and a "magnetic concentration-washing process" is proposed to effectively reduce the interference of dye pollution.
