CHAPTER 7. New Chip-based Technologies for Rapid Analysis of Food Contaminants

Chip-based technology refers to methods that combine sample handling and signal transduction methods in a small, integrated package with the overall goal of providing rapid, portable testing capabilities. This chapter provides an overview of new chip-based technologies and their function in the context of food contaminant, ingredient, and adulterant testing, with a specific focus on rapid antibody-based test methods. The chapter first provides a description of key design elements that should be considered during development of integrated chip-based solutions, including sample compatibility, detection methods, and robustness. Cost and operating environment constraints are highlighted. Select examples of chip-based technology implementations are discussed in detail to provide insight into the range of design issues that must be considered for rapid food contaminant testing applications.
