In this work, amino functionalized CdSe-silica core-shell nanoparticles (NH -CdSe@SiO NPs) were constructed as probe to detect picric acid (PA). The CdSe QDs were embedded in SiO nanoparticles and modified with amino groups on the surface. The nitro explosives are electron deficient in nature, which...
