Trends of Novel Functional Nanomaterials for Analysis of Sulfonamide Residues in Food Products

Abstract

The residues of sulfonamides (SAs) may transfer to the human body through the food chain, causing risks to human health. Therefore, it is of significance to address the SA residues in food products. Recently, the development of nanomaterial adsorbents with fast adsorption, low toxicity, robustness, and reusability has attracted much attention. CiteSpace software was used in this work to analyze studies on the detection of SAs in the past five years. Furthermore, novel nanomaterials, including magnetic nanomaterials, metal_organic framework materials (MOFs), and covalent organic framework materials (COFs), are reviewed in detail for extraction and analysis of SAs in food, showing the advantages in the adsorption and analysis performance of these nanomaterials. Challenges and prospects of related research are also discussed to clarify the future directions for the achievement of food safety. This review is expected to provide new insights for the development of efficient adsorbents and analytical methods for food pollutants with potential applications.
