DOI: 10.1002/elps.202000243 The cover picture shows a novel purification method using magnetic solid‐phase extraction (MSPE) based on magnetic carbon nanotube dummy molecularly imprinted polymer (MCNTMIP) nanocomposite, which was used to investigate separation and enrichment of sulfonamide antibiotics (SAs) in fish and shrimp samples. Combined with ultra‐high performance liquid chromatography tandem mass spectrometry (UPLC‐MS/MS), a rapid, sensitive, efficient MSPE method with characteristic high specificity to SAs has been developed for the purification step to avoid interference from complex matrices.
