Abstract
Food safety is a worldwide problem and ensuring food safety requires strict monitoring of toxins, antibiotics, and bacteria. Thus, sensitive methods of analysis to determine the types and residues of harmful components in food are needed. Point-of-care sensors have been abundantly developed over the last two decades and are proven to be innovative to analyze the contaminants present in food samples both quantitatively and qualitatively. In this book chapter, an overview of aptamer-based optical methods for monitoring food safety is provided. This chapter will focus on optical biosensing techniques such as UV-visible spectroscopy, fluorescence spectroscopy, surface-enhanced Raman spectroscopy, and photonic crystals. The principle, mechanism, advantages, and limitations of each technique are described with an ample number of examples.
