Ensuring food safety and authenticity is a pressing global concern. This chapter provides a comprehensive overview of advanced rapid, on-site detection technologies targeting foodborne hazards, including pathogens, toxins, chemical contaminants, and authenticity issues such as adulteration and species fraud. Key aspects of these technologies include signal amplification strategies like catalytic hairpin assembly (CHA) and nanozyme-enhanced systems, as well as signal output platforms encompassing colorimetric, electrochemical, and fluorescence-based methods. The chapter also explores the emerging role of nanopore-based sensing as a novel signal output platform, emphasizing its single-molecule precision and broad applicability. By integrating laboratory innovations with practical field applications, this chapter underscores the potential of these technologies to address challenges in food safety and authenticity monitoring effectively.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.
