A magnetic solid-phase extraction method (MSPE) was developed to pre-concentrate and cleanup clenbuterol (CLE) from pork muscle. Novel sulfonated polystyrene magnetic nanobeads (spMNBs) were synthesized via a one-pot emulsion copolymerization method by using divinylbenzene, styrene, and sodium styrene sulfonate in the presence of oleic acid-modified and(More)
The performance of fluorescent microsphere immunochromatographic assay (FM-ICA) and quantum-dot submicrobead immunochromatographic assay (QB-ICA) was systematically and comprehensively compared in quantitative detection of aflatoxin M1 in milk. Under optimum conditions, the advantages of FM-ICA include lower limit of detection of 42.3 pg/mL with better(More)
Amantadine (AMD) is a prohibitive veterinary medicine in the entire world. In this study, a sensitive colloidal gold immunochromatographic assay (CGICA) was established for the rapid semi-quantitative detection of AMD in chicken muscle. Under optimal conditions, the detection results were obtained in 12min with a limit of detection for 1.80ng/mL. CGICA(More)
