Dispersive solid-phase extraction and immunoassay with internal reference calibration using fatty acid-coated inorganic fluorescent nanoparticles

Cháfer Pericás, María Consuelo; Balaguer, Ángel; Maquieira Catala, Ángel; Puchades Pla, Rosa (Elsevier Masson, 2013)

Dispersive solid-phase extraction (dSPE) using fatty acid-coated Eu2O3 nanoparticles (NPs) was developed, and a direct immunoassay was carried out employing these NPs as support. Secondary antibodies labeled with fluorophore ...
Multiresidue determination of antibiotics in feed and fish samples for food safety evaluation. Comparison of immunoassay vs LC-MS-MS

Cháfer Pericás, María Consuelo; Maquieira Catala, Ángel; Puchades, Rosa; Miralles, Javier; Moreno, Amelia (Elsevier, 2011-06)

[EN] Antibiotic residues (sulfonamides and tetracyclines) were determined in Gilthead sea bream (Sparus aurata) and feed samples by means of immunoassays and LC-MS-MS (liquid chromatography-mass spectrometry 2). A preliminary ...
