中文摘要:

      瘦肉精、“毒”奶粉、染色馒头等食品安全事件屡屡发生, 严重危害人体健康与生命安全。同时, 农兽药残留、重金属超标、非法添加物等食品安全问题已成为社会热点话题, 对这些食品有害物的监测和检测必不可少。因此, 建立健全食品安全检测技术体系, 对保障食品质量安全和人们身体健康至关重要。光子晶体由于其自身的光学特性及光子带隙的可调控性, 在食品有毒有害物质的检测研究中引起广泛关注, 可作为可视化、无标记的快速检测材料。本文综述了光子晶体材料的优势及其在食品中有害物检测中的研究进展, 简要介绍了光子晶体材料在富集纯化、防伪标签方面的应用, 并展望了光子晶体传感材料的未来发展方向, 为光子晶体材料在食品安全领域的研究提供参考与启示。

英文摘要:

      Food safety incidents have been occurred frequently, such as “clenbuterol”, poisonous milk powder, tainted steamed buns, which endangers human health and life safety seriously. Meanwhile, residues of pesticides and veterinary drugs, excessive heavy metals, illegal additives and other food safety issues have become a hot topic in society. It is essential for the monitoring and detection of the harmful substances in food. Therefore, the establishment of a sound food safety detection technology system is essential to ensure food quality and safety and people’s health. Photonic crystals have attracted wide attention in the research of detection of toxic and harmful substances in food due to their own optical properties and adjustable photonic band gap, which can be used as visualized and label-free rapid detection materials. This paper reviewed the advantages of photonic crystal materials and the research progress for the detection of harmful substances in food, introduced the applications of photonic crystal materials in enrichment purification and anti-counterfeit labeling, and foreseen the future development direction of photonic crystal sensing materials , so as to provide reference and inspiration for the research of photonic crystal materials in the field of food safety.
