Abstract:

An ultrasensitive competitive-type electrochemiluminescence immunoassay for the mycotoxin zearalenone is described. The method is based on the use of (a) a mimotope peptide that was selected from a phage displayed peptide library and used to substitute ZEN for designing the competitive assay; (b) NiFe2O4 nanotubes with large specific surface area loaded with the ECL probe Ru(bpy)3 2+; and (c) poly(vinylpyrrolidone) (PVP)-assisted synthesis of TiO2 mesocrystals that acts as the sensing platform and support for antibody immobilization. Under the optimized conditions and at an ECL working potential of 1.1 V, a linear response is found for ZEN in the 0.1 to 1.0 × 10−5 ng·mL−1 concentration range with a detection limit as low as 3.3 fg·mL−1.
