Back Cover: Ternary Hybrid [gamma]-Fe2O3/CrVI/Amine Oxidase Nanostructure for Electrochemical Sensing: Application for Polyamine Detection in Tumor Tissue

Polyamine detector: Dichromate binds to surface-active maghemite nanoparticles (SAMN) to form a stable core-shell nanostructure (SAMN@CrVI), which is an excellent electrocatalyst for hydrogen peroxide reduction. Bovine serum amine oxidase was immobilized on SAMN@CrVI to give a ternary hybrid nanostructured catalyst for polyamine oxidation, which was used to develop a reagentless, fast, inexpensive, and interference-free polyamine biosensor for the discrimination of tumor tissue from healthy tissue in human crude liver extracts (see figure).
