“…This combination made possible the study of mycotoxins by CZE-UV, by simply using a neutral pH BGE with a small addition of βCD, eliminating matrix interference and offering a rapid and simple clean up with high selectivity. The pre-concentration procedure allowed sensitivity values higher (30 μg/Kg) than those obtained with the most recent optimizations of SLM procedures, combined with different analytical approaches, such as Surface-Enhanced Raman Spectroscopy (SERS) or HPLC-MS [ 57 ].…”

“…Compared with the traditional immunoaffinity column, SLM extraction shows the advantages of high recovery efficiency, low solvent consumption and user‐friendly operating procedure. Therefore, SLM combined with SERS (SLM‐SERS) had been applied for rapidly detecting OTA in wines (see Figure 8B) (Rostami et al., 2020). Due to the complexity of wine samples, the presence of matrix interference in wines would lead to the absence of SERS signal of OTA.…”

“…The ingestion of these metabolites is a potential threat to humans and animals. (1) Among these metabolites, ochratoxin A (OTA) is one of the most common and harmful substances, (2) and is nephrotoxic, immunosuppressive, and carcinogenic. (3) Hence, a sensitive and efficient analytical method is required for its determination.…”
