This article developed a novel electrochemical immunosensor for the specific detection of aflatoxin B1 (AFB1). Amino‐functionalized iron oxide nanoparticles (Fe3O4‐NH2) were synthesized. Fe3O4‐NH2 were chemically bound on self‐assembly monolayers (SAMs) of mercaptobenzoic acid (MBA). Finally, polyclonal antibodies (pAb) were immobilized on Fe3O4‐NH2‐MBA. The sensor system was evaluated through atomic...
The authors describe a label-free electrochemical biosensor based on CNTs for picogram range detection of the food carcinogen aflatoxin B1 (AFB1). A gold electrode was modified with a cysteine (Cys) self-assembled layer, and carboxyl-functionalized carbon nanotubes were covalently attached to Cys for the subsequent tethering of antibody against AFB1 (anti-AFB1). Topographical images of the biosensor...
