Recent advances in nanomaterial‐assisted electrochemical sensors for food safety analysis

Abstract

Food safety as a public health issue has aroused worldwide concern. Food safety risks caused by the existence of food safety hazards in food may occur in all stages of the food supply chain. Thus, great emphasis is placed on sensitive, selective, and convenient analytical methods of various food safety hazards in food. At present, nanomaterials are at the forefront of various electrochemical sensing applications. Given their unique physical, chemical, and biological characteristics, nanomaterials are considered perfect candidates for the design of electrode surface to construct electrochemical sensors with excellent analytical performance. With the assistance of nanomaterials, electrochemical sensors are a potential alternative to conventional methods of food safety analysis. This review focuses on current research achievements of nanomaterial‐assisted electrochemical sensors for food safety analysis reported in recent 5 years. It highlights the different detection mechanisms for analytes, flexible sensing strategies based on nanomaterials, and portable miniaturized electrochemical devices. Finally, the challenges and limitations in the design of electrochemical sensors for food safety analysis are also discussed.

Sowing kernels for food safety: Importance of rapid on‐site detction of pesticide residues in agricultural foods

“…Smartphones and integrated electrochemical devices are designated as POC technological platforms for on-site recognition of chemical pesticides (Comnea-Stancu et al, 2021;Gu et al, 2022;Umapathi, Ghoreishian, et al, 2022;.…”

“…The colorimetric detection of pesticides based on nanoparticle aggregation utilizes the potential of both optical and analytical nanotechnology. Nanoparticles have been used as probes for colorimetric assays via functionalization, “host‐guest” chemistry, and aggregation (N. Choi et al., 2021; Fang et al., 2021; Gu et al., 2022; Lu et al., 2019; Patel et al., 2021; Sahoo et al., 2021; Umapathi et al., 2021; Umapathi, Ghoreishian, et al., 2022; Umapathi, Park, et al., 2022; L. Wang et al., 2021; T. Yan et al., 2021; Zhang et al., 2021).…”

“…The coupling of fluorescent nanomaterials with functional materials and advanced recognition elements can provide highly attractive opportunities for sensing pesticide residues. This methodology improved the sensing performance of the device (N. Choi et al., 2021; Danial et al., 2021; Fang et al., 2021; Gu et al., 2022; Ma et al., 2022; Patel et al., 2021; Prabhu et al., 2021; Sahoo et al., 2021; L. Wang et al., 2021; Y. Yan et al., 2021; Zhang et al., 2021).…”

A strategy for reducing acrylamide content in wheat bread by combining acidification rate and prerequisite substance content of Lactobacillus and Saccharomyces cerevisiae

“…The MR is often used by food manufacturer to develop appealing aromas, color or texture in baked foods. However, despite some positive aspects, the MR could decrease the nutritional value of baked foods, generate potentially harmful compounds ( Neda et al, 2021 ; Gu et al,2022 ). In 1994, THE International Agency for Research on Cancer (IARC) listed AM as a “robable human carcinogen (Class 2A)" ( IARC, 1994 ).…”

Electrochemical determination of synephrine by using nafion/UiO-66/graphene-modified screen-printed carbon electrode

“…As a kind of ultrasensitive detection method, electrochemical sensors for synephrine are attractive to researchers because of their convenience, portability, and sensitivity ( Wang et al, 2021 ; Yan et al, 2022 ). Through the customizations in size and composition of sensors, in the combination of the designed small and portable workstation, a preliminary and rapid detection of synephrine could be completed in the field, which would save a lot of time and labor in agricultural research ( Gu et al, 2022 ). The screen-printed carbon electrode (SPCE) is a type of inexpensive and versatile sensor.…”
