表面增强拉曼光谱在食品污染物快速检测中的应用

随着科技的发展,食品的种类越来越丰富,随之而来的问题是食品中引入的污染物也越来越复杂,这使得食品安全成为当今全球关注的一个重要话题,快速有效地检测食品中污染物已然成为食品检测的热点。表面增强拉曼光谱(surface-enhanced Raman spectroscopy, SERS)由于其极高的灵敏度、快速检测、指纹图谱解释能力,以及高达单分子级别的检测水平,逐渐成为检测食品中污染物的常用方法。本文针对SERS基底的发展现状,如特殊形态金属纳米颗粒和固相SERS平台,以及SERS在农兽药,掺假,天然毒素以及食源性病原体等污染物中的检测方法进行了论述,以期为表面增强拉曼光谱未来在食品污染物快速检测中的应用提供参考。

Application of surface-enhanced Raman spectroscopy in the rapid detection of food contaminants

With the development of science and technology, the types of food are becoming more and more abundant, and the problem that follows is that the contaminants introduced in food are becoming more and more complex, which makes food safety an important topic of global concern today, and rapid and effective detection Contaminants in food have become a hot spot in food testing. Surface-enhanced Raman spectroscopy (SERS) has gradually become a common method for detecting contaminants in food due to its extremely high sensitivity, rapid detection, fingerprint interpretation capabilities, and detection levels up to the molecular level. The development status of SERS substrates based on high "hot spots", such as special morphological metal nanoparticles, solid-phase SERS platform, and SERS detection methods in agricultural and veterinary drugs, adulteration, natural toxins, and food-borne pathogens and other related food contaminants was discussed in this review.
