Food contamination poses serious health risks, compelling the discovery of new methods to guarantee regulatory compliance and build consumer conviction. Surface Enhanced Raman Spectroscopy (SERS) has come into sight as a sophisticated approach for the ultrasensitive discovery of toxins in food and water, proposing non-destructive, quick, and precise analysis. Instantaneously, quantum dots (QDs) are astonishing nanomaterials, characterized by distinctive attributes such as quantum confinement and optical photostability. This article extends a decisive outline of SERS technology, pointing out its amalgamation with QDs and discussing numerous augmentation approaches i.e., chemical enhancement, electromagnetic enhancement, Van Hove singularities, the Brus equation, Förster resonance energy transfer, band gap energy, and quantum yield. The amalgamation of SERS with QDs commands an important promise in international food security and conservational sustainability. Nevertheless, QDs provide several compensations, they also aspect a few concerns, counting probable toxicity, stability problems, and predisposition to interference. To tackle these items, further research is required to synthesize safer, more stable QD materials and to refine protocols for practical real-world applications. While some reviews on SERS have been published recently, to our knowledge, the current review is the first one dedicated to QDs-assisted SERS in food safety.
食品污染带来严重的健康风险，这促使人们去探索新方法以确保符合监管要求并增强消费者信心。表面增强拉曼光谱法（SERS）已成为一种用于超灵敏检测食品和水中毒素的精密方法，具有无损、快速且精确的分析特点。与此同时，量子点（QDs）是令人瞩目的纳米材料，具有量子限域和光学光稳定性等独特特性。本文概述了SERS技术的关键要点，指出其与量子点的结合，并讨论了多种增强方法，即化学增强、电磁增强、范霍夫奇点、布鲁斯方程、福斯特共振能量转移、带隙能量和量子产率。SERS与量子点的结合在全球食品安全和保护可持续性方面有着重要前景。然而，量子点虽有诸多优势，但也存在一些问题，包括潜在毒性、稳定性问题以及易受干扰性。为解决这些问题，需要进一步开展研究，以合成更安全、更稳定的量子点材料，并完善实际应用的方案。尽管最近已发表了一些关于SERS的综述，但据我们所知，当前这篇综述是第一篇专门针对食品安全中量子点辅助SERS的综述。
