摘要：

We demonstrate for the first time that bifunctional Au-Fe3O4 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.
