Increased consumption of processed foods, globalization, and spiraling food prices have led to many challenges such as food quality, food safety, food adulteration, and food contamination. Food quality and food safety are the two most important aspects focused in food processing industry. Analytical procedures and instrumentation are sufficiently equipped for the detection of ions, molecules, or microorganisms with good sensitivity and selectivity. However, these instruments and their services are expensive and cannot be operated by the common man without instrumentation knowledge. Hence, there is a need for simple, affordable, field applicable sensor systems with sufficient analytical performance for the evaluation of food safety and quality. Biosensors are capable of fulfilling the above requirements, and with the advent of nanotechnology, their scope for application in multiple fields has been revived. Different classes of nanomaterials are integrated into various biosensor platforms and found to enhance their analytical performance.
