Abstract:

With the increasing attention paid by the country and its people to food safety, various principles and techniques
for food safety detection have continued to be developed to meet the requirements of different occasions usually by
combination with special materials or new techniques. Carbon nanotube technology (CNT) has seen wide applications in
multidisciplinary fields with excellent performance and promising prospects. Its applications in food safety detection are
summarized in two aspects: integration with traditional detection technologies for food safety and development of biosensors
based on carbon nanotubes. Accordingly, automatic and micro-dimensional food safety detection techniques have been
developed with the advantages of high sensitivity, stability, low costs, long lifespan, high efficiency, rapidity, etc.

Key words: food safety detection, carbon nanotube technology (CNT), biosensor
