Gold nanoparticle-based lateral flow immunoassay for the rapid detection of flutriafol residues in food

We developed gold nanoparticle-based lateral flow immunoassay for the rapid detection of flutriafol residues in food, with a visual LOD in rice, tomatoes, and grapes of 0.5 mg kg −1 , 0.2 mg kg −1 and 0.5 mg kg −1 , respectively.
