  • Title: Surface-imprinted magnetic nanoparticles for the selective enrichment and fast separation of fluoroquinolones in human serum.
    Author: Su L, Jin Y, Huang Y, Zhao R.
    Journal: J Sep Sci; 2017 May; 40(10):2269-2277. PubMed ID: 28371546.
    Abstract:
    Surface enrofloxacin-imprinted magnetic nanoparticles were prepared for the selective recognition and fast separation of fluoroquinolones in human serum by surface-initiated reversible addition fragmentation chain transfer polymerization. The surface morphology and imprinted behavior were investigated and optimized. The living/controlled nature of reversible addition-fragmentation chain transfer polymerization reaction allowed the successful construction of well-defined imprinted polymer layer outside the Fe3 O4 core. Such molecularly imprinted polymers exhibited superparamagnetic properties and specific recognition toward fluoroquinolones. Combined with reversed-phase high-performance liquid chromatography, the prepared molecularly imprinted polymers were used for the selective enrichment and analysis of fluoroquinolones in human serum samples. The recoveries of four fluoroquinolones were 86.8-95.3% with relative standard deviations of 2.0-6.8% (n = 3). Such magnetic molecularly imprinted polymers have great prospects in the separation and enrichment of trace analysts in complex biological samples.
