Nanotechnology and food quality control.
The preparation and attractive performance of nanomaterials for innovative detection schemes of food related compounds are described. Nickel nanowires growths by the template procedure were used for magnetoswitchable control of electrochemical processes of sugar-like compounds at the electrode surface. Gold nanoparticles were also prepared by reducing a gold solution with different phenolic compounds. The different antioxidant power of these compounds allow to modulate the kinetic growth of gold nanoparticles. Finally, an index of the antioxidant power based on the growth of gold nanoparticle is reported.
