Magnetic nanoparticles solid phase extraction for determination of ochratoxin A in cereals using high-performance liquid chromatography with fluorescence detection
TL;DR: A new, simple, fast, and environmental friendly sample preconcentration technique based on the modified Fe3O4 nanoparticles has been developed for extraction, and determination of ochratoxin A (OTA).
Journal ArticleDOI
Dispersive micro-solid phase extraction using magnetic nanoparticle modified multi-walled carbon nanotubes coupled with surfactant-enhanced spectrofluorimetry for sensitive determination of lomefloxacin and ofloxacin from biological samples.
TL;DR: The D-μ-SPE procedure coupled with surfactant-enhanced spectrofluorimetric detection was developed and successfully applied to the extraction and preconcentration of these drugs in biological (plasma and urine) samples.
Journal ArticleDOI
Application of dispersive liquid-liquid microextraction coupled with vortex-assisted hydrophobic magnetic nanoparticles based solid-phase extraction for determination of aflatoxin M1 in milk samples by sensitive micelle enhanced spectrofluorimetry.
TL;DR: An efficient, simple and fast low-density solvent based dispersive liquid-liquid microextraction followed by vortex-assisted dispersive solid phase extraction (VA-D-SPE) has been developed as a new approach for extraction and preconcentration of aflatoxin M1 in milk samples prior to its micelle enhanced spectrofluorimetic determination.
Journal ArticleDOI
Switchable on/off drug release from gold nanoparticles-grafted dual light- and temperature-responsive hydrogel for controlled drug delivery.
TL;DR: A switchable dual light- and temperature-responsive drug carrier using gold nanoparticles (Au NPs)-grafted poly(dimethylacrylamide-co-acylamide)/poly acrylic acid [P(DMA- co-AAm)/PAAc] hydrogel was prepared by free radical polymerization procedure using N,N-methylenebisacryamide as cross-linker and ammonium persulfate as initiator.
Journal ArticleDOI
Mixed supramolecular hemimicelles aggregates and magnetic carrier technology for solid phase extraction of ibuprofen in environmental samples prior to its HPLC-UV determination
TL;DR: In this article, a solid phase extraction method based on the adsorption of cetyltrimethylammonium bromide (CTAB) on the surface of Fe 3 O 4 nanoparticle adsorbent was developed for determination of ibuprofen in environmental samples.
