| Popis: | One of the key challenges to both control foodstuff composition and detect chemical or biological contaminants in food is the availability of selective, sensitive, and reliable analytical methods. In this context, electrochemical biosensors are particularly attractive due to their low-cost, high sensitivity, and selectivity. They can be easily miniaturized and integrated in high density arrays for multianalyte and high throughput analysis. To improve their sensitivity and robustness, different strategies have been developed, including the incorporation of nanomaterials such as gold or magnetic nanoparticles, carbon-based nanostructures (eg, nanotubes, graphene). These nano-objects offer high surface areas and can be used as platforms to enhance bioreceptors loading and stability, also serving as relays for electron transfer between the biomolecules and the electrode. In this chapter, new trends in nanomaterial-based electrochemical biosensors for food analysis are reviewed, focusing on the determination of major contaminants, that is, foodborne pathogens, toxins, veterinary drug residues, and pesticides. |
