Biotoxins, toxic substances produced by living organisms, are widely present in food and pose a major threat to human health. Traditional detection methods, such as gas chromatography-mass spectrometry (GC-MS) enzyme-linked immunosorbent assay (ELISA), often suffer from limitations including complex sample preparation, high costs, lengthy analysis times. In response, surface-enhanced Raman spectroscopy (SERS) has emerged highly sensitive specific analytical tool for the of biotoxins. This review highlights recent progress multimodal technologies based on SERS, focusing design classification materials optimize construction SERS substrates. The integration with other modalities, fluorescence, colorimetry, electrochemistry, is discussed enhance accuracy diversity biotoxin detection. Finally, critically assesses current challenges future prospects technology, particularly real-time safety monitoring on-site diagnostics, offering critical insights guide research directions.
