“…In general, the channel model prepared by this method has a wide range of application prospects in the elimination of organic and inorganic pollutants in water. In addition, Ma et al used a simple and efficient layer-by-layer functionalization method to deposit positively charged polyethylenimine (PEI) and negatively charged poly(acrylic acid) (PAA) on the inner surface of polyelectrolyte-functionalized monotonical nanochannels to increase the carboxyl density and form PAA-Ce 3+ chelation in the nanochannels, enabling the ultrasensitive detection of Ce 3+ at 1 nM ∼ 10 –3 nM, with a detection limit of 1 nM and 95.0% in ammonia nitrogen water samples recovery of Ce 3+ . The nanochannel sensors prepared by these methods can not only realize the rapid, sensitive and specific detection of rare earth ions and ensure food safety, but also can be used for the recovery of rare earth ions, providing a valuable platform for the reuse of rare earth resources.…”

Food quality and safety are related to the health and safety of people, and food hazards are important influencing factors affecting food safety. It is strongly necessary to develop food safety rapid detection technology to ensure food safety. As a new detection technology, artificial nanochannel-based electrochemical and other methods have the advantages of being real-time, simple, and sensitive and are widely used in the detection of food hazards. In this paper, we review artificial nanochannel sensors as a new detection technology in food safety for different types of food hazards: biological hazards (bacteria, toxins, viruses) and chemical hazards (heavy metals, organic pollutants, food additives). At the same time, we critically discuss the advantages and disadvantages of artificial nanochannel sensor detection, as well as the restrictions and solutions of detection, and finally look forward to the challenges and development prospects of food safety detection technology based on the limitations of artificial nanochannel detection. We expect to provide a theoretical basis and inspiration for the development of rapid real-time detection technology for food hazards and the production of portable detection equipment in the future.
