Azo dyes as widely applied food colorants are popular for their stability and affordability. On the other hand, many of these dyes can have harmful impacts on living organs, which underscores the need to control the content of this group of dyes in food. Among the various analytical approaches for detecting the azo dyes, special attention has been paid to electro-analytical techniques for reasons such as admirable sensitivity, excellent selectivity, reproducibility, miniaturization, green nature, low cost, less time to prepare and detect of specimens and the ability to modify the electrode. Satisfactory results have been obtained so far for carbon-based nanomaterials in the fabrication of electrochemical sensing systems in detecting the levels of these materials in various specimens. The purpose of this review article is to investigate carbon nanomaterial-supported techniques for electrochemical sensing systems on the analysis of azo dyes in food samples in terms of carbon nanomaterials used, like carbon nanotubes (CNT) and graphene (Gr).
偶氮染料作为广泛应用的食品着色剂，因其稳定性和价格适宜而受到青睐。然而，许多这类染料可能对活体器官造成有害影响，这凸显了控制这组染料在食品中含量的必要性。在检测偶氮染料的各种分析方法中，电化学分析技术因其令人瞩目的灵敏度、出色的选择性、重现性、小型化、绿色环保、低成本、标本制备和检测时间短以及修饰电极的能力而受到特别关注。迄今为止，在构建电化学传感系统以检测各种标本中这些物质的水平方面，基于碳纳米材料的方法已经取得了令人满意的结果。本文综述了基于碳纳米材料的技术在食品样品中偶氮染料电化学传感系统分析方面的应用，重点介绍了用于构建电化学传感系统的碳纳米材料，如碳纳米管（CNT）和石墨烯（Gr）。
