Haibing Li and co-workers at the Central China Normal University developed a versatile yet simple strategy for the fabrication of a highly selective and sensitive fenamithion probe based on Rhodamine B modified silver nanoparticles. They propose and prove a novel amino-containing analyte-induced etching mechanism to explain their results. This system allows prompt on-site and real-time detection of the pesticide, fenamithion, in real vegetable and water samples, with high sensitivity and excellent anti-disturbance ability.
