Surface-enhanced Raman spectroscopy (SERS) is an advanced Raman technique that enhances the vibrational spectrum of molecules adsorbed on or in the vicinity of metal particles and/or surfaces. Because of its readiness, sensitivity, and minimum sample preparation requirements, SERS is being considered as a powerful technique for food inspection. Key aspects of food-safety assurance, spectroscopy methods, and SERS are briefly discussed in an extended introduction of this review. The recent and potential advances in SERS are highlighted in sections that deal with the (a) detection of food-borne pathogenic microorganisms and (b) the detection of food contaminants and adulteration, concentrated specifically on antibiotics, drugs, hormones, melamine, and pesticides. This review provides an outlook of the work done and a perspective on the future directions of SERS as a reliable tool for food-safety assessment.
表面增强拉曼光谱(SERS)是一种先进的拉曼技术,可增强吸附在金属颗粒和/或表面上或附近的分子的振动光谱。由于其易于使用、灵敏度高和最小的样品制备要求,SERS 被认为是一种用于食品检测的强大技术。在本综述的扩展介绍中,简要讨论了食品安全保证的关键方面、光谱方法和 SERS。在涉及(a)检测食源性致病微生物和(b)检测食品污染物和掺假的部分中,突出了 SERS 的最新和潜在进展,重点是抗生素、药物、激素、三聚氰胺和农药。本综述提供了对所做工作的展望和对 SERS 作为食品安全评估可靠工具的未来方向的看法。
