A new and sensitive method based on magnetic solid phase extraction (MSPE) with antibody-free modified magnetic nanoparticles (MMNPs) followed by high performance liquid chromatography with post-column derivatization and fluorescence detection (HPLC-PCD-FD) has been developed for the separation and determination of aflatoxin M1 (AFM1) in liquid milk.
