Electrochemical Affinity Biosensors in Food Safety

摘要: Safety and quality are key issues of today’s food industry. Since the chain is becoming more complex, powerful analytical methods required to verify performance safety systems. Indeed, such require high sensitivity, selectivity, ability for rapid implementation capability automatic screening. Electroanalytical chemistry has, decades, played a relevant role in assessment, taking significance over time solution problems. At present, electrochemical evident. This large part due results obtained by combining attractive advantages transduction strategies (in terms relatively simple hardware, versatility, interface with logging feasibility application outside laboratory environment) those from biosensors technology. Important examples enzyme dedicated determination glucose, alcohol or cholesterol important examples. In addition, other types different biosensing approaches have emerged strongly last years. Among these, involving affinity interactions been shown possess number applications. Therefore, immunosensors DNA-based widely used determine major minor components foodstuffs, providing sufficient data evaluate freshness, raw materials, origin samples, as well variety compounds at trace levels related micotoxins, allergens, drugs residues pathogen microorganisms. review discusses some critical latest advances this area, pointing out methodologies measurement techniques, including use nanostructured electrodes signal amplification.
