Validation of a rapid method of analysis using ultrahigh-performance liquid chromatography - tandem mass spectrometry for nitrogen-rich adulterants in nutritional food ingredients.

J. Chromatogr. A. 1373 , 106-13, (2014)

A method for the rapid quantification of 9 potential nitrogen-rich economic adulterants (dicyandiamide, urea, biuret, cyromazine, amidinourea, ammeline, amidinourea, melamine, and cyanuric acid) in five milk and soy derived nutritional ingredients, i.e. whole...

Colorimetric detection of melamine in milk by citrate-stabilized gold nanoparticles.

Anal. Biochem. 456 , 43-9, (2014)

Here, we report a simple and sensitive colorimetric method for detection of melamine in milk using gold nanoparticles (AuNPs). AuNPs of 21-nm size were synthesized by the citrate reduction method. The method is based on the principle that the melamine causes ...

Genotoxicity assessment of melamine in the in vivo Pig-a mutation assay and in a standard battery of assays.

Mutat. Res. Genet. Toxicol. Environ. Mutagen. 777 , 62-7, (2015)

The genotoxicity of melamine was evaluated with the combined Pig-a mutation/micronucleus assay, the bacterial reverse mutation assay, and the in vitro cytokinesis-block micronucleus assay (CBMN). Five groups of six- to eight-week-old male Sprague-Dawley (SD) ...

Detection of melamine in milk using molecularly imprinted polymers-surface enhanced Raman spectroscopy.

Food Chem. 176 , 123-9, (2015)

A novel biosensor combining molecularly imprinted polymers and surface-enhanced Raman spectroscopy (MIPs-SERS) determines melamine in whole milk. MIPs were synthesized by bulk polymerization of melamine (template), methacrylic acid (functional monomer), ethyl...

Performance-enhancing methods for Au film over nanosphere surface-enhanced Raman scattering substrate and melamine detection application.

PLoS ONE 9(6) , e97976, (2014)

A new high-performance surface-enhanced Raman scattering (SERS) substrate with extremely high SERS activity was produced. This SERS substrate combines the advantages of Au film over nanosphere (AuFON) substrate and Ag nanoparticles (AgNPs). A three order enha...

Nephrotoxic potential and toxicokinetics of melamine combined with cyanuric Acid in rats.

J. Toxicol. Environ. Health A 77(22-24) , 1346-58, (2014)

To investigate the nephrotoxic potential of melamine (MEL) and cyanuric acid (CA) in male Sprague-Dawley rats, 7-d repeated-dose studies were performed. The experimental groups of MEL100 and CA100 were orally administered with MEL and CA at 100 mg/kg/d for 7 ...

Plasma-based ambient sampling/ionization/transmission integrated source for mass spectrometry.

Analyst 139(21) , 5387-92, (2014)

Better sensitivity and interface of ambient sampling/ionization mass spectrometry remain a challenge. Herein, a novel, plasma-based, ambient sampling/ionization/transmission (PASIT) integrated source in a pin-to-funnel configuration was developed for the sens...

Melamine nanosensing with chondroitin sulfate-reduced gold nanoparticles.

J. Nanosci. Nanotechnol. 13(12) , 8229-38, (2013)

Gold nanoparticles were green-synthesized using a glycosaminoglycan, chondroitin sulfate, as the reducing agent by mixing Au3+ and chondroitin sulfate under heating. Chondroitin sulfate-reduced gold nanoparticles were characterized by UV-Vis spectrophotometry...

Synthesis of g-C3N4/Fe3O4 nanocomposites and application as a new sorbent for solid phase extraction of polycyclic aromatic hydrocarbons in water samples.

Talanta 132 , 922-8, (2014)

An easy preparation of g-C3N4/Fe3O4 nanocomposites by chemical co-precipitation has been demonstrated. The as-prepared materials were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and thermogravi...

Structural and vibrational spectral investigations of melaminium maleate monohydrate by FTIR, FT-Raman and quantum chemical calculations.
