It is widely accepted that nanotechnology attracted more interest because of various values that nanomaterial applications offers in different fields. Recently, researchers have proposed nanomaterials based electrochemical sensors and biosensors as one of the potent alternatives or supplementary analytical tools to the conventional detection procedures that consumes a lot of time. Among different nanomaterials, researchers largely considered magnetic nanomaterials (MNMs) for developing and fabricating the electrochemical (bio)sensors for numerous utilizations. Among several factors, healthier and higher quality foods are the most important preferences of consumers and manufacturers. For this reason, developing new techniques for rapid, precise as well as sensitive determination of components or contaminants of foods is very important. Therefore, developing the new electrochemical (bio)sensors in food analysis is one of the key and effervescent research fields. In this review, firstly, we presented the properties and synthesis strategies of MNMs. Then, we summarized some of the recently developed MNMs-based electrochemical (bio)sensors for food analysis including detecting the antioxidants, synthetic food colorants, pesticides, heavy metal ions, antibiotics and other analytes (bisphenol A, nitrite and aflatoxins) from 2010 to 2020. Finally, the present review described advantages, challenges as well as future directions in this field.
人们普遍认为，由于纳米材料应用在不同领域具有多种价值，纳米技术引起了更多关注。最近，研究人员提出基于纳米材料的电化学传感器和生物传感器，作为传统检测程序的有效替代方案或补充分析工具，传统检测程序耗时较长。在不同的纳米材料中，研究人员在很大程度上考虑使用磁性纳米材料（MNMs）来开发和制造用于多种用途的电化学（生物）传感器。在诸多因素中，更健康、更高质量的食品是消费者和制造商最重要的偏好。因此，开发快速、精确且灵敏地测定食品成分或污染物的新技术非常重要。所以，开发用于食品分析的新型电化学（生物）传感器是关键且活跃的研究领域之一。在本综述中，首先，我们介绍了磁性纳米材料的性质和合成策略。然后，我们总结了一些最近开发的基于磁性纳米材料的用于食品分析的电化学（生物）传感器，包括在2010年至2020年期间检测抗氧化剂、合成食用色素、农药、重金属离子、抗生素以及其他分析物（双酚A、亚硝酸盐和黄曲霉毒素）。最后，本综述描述了该领域的优势、挑战以及未来方向。
