Metallomics, 2011
The analysis of metal-binding proteins requires careful sample manipulation to ensure that the metal-protein complex remains in its native state and the metal retention is preserved during sample preparation or analysis. Chemical analysis for the metal content in proteins typically involves some type of liquid chromatography/electrophoresis separation ...

Magnetic (nano)materials as an useful tool for sample preparation in analytical methods. A review
Analytical Methods, 2013This review, with more than 170 references, presents a general overview of the use of magnetic nanoparticles (MNPs) to perform sample preparation. In this way, the main types of MNPs used for this purpose, such as magnetic molecularly imprinted polymer (MMIP), noble metal coated MNPs, carbon nanotubes (CNTs), quantum dots (QDs), silica, and surfactant ...

Over the past decade, the risk assessment of carcinogenic and genotoxic compounds in food has received increasing attention due to their capability of producing cancer by altering the genetic material of target cells directly in humans. Compounds that are both carcinogenic and genotoxic often presented at low levels in food, therefore, it is strenuous ...

Food Additives & Contaminants: Part A, 2017
The world population is increasing and there is a growing demand for food, leading to intensification of farming methods and a requirement for more coadjuvants. Potential high profits sometimes lead to fraudulent use of drugs and pesticides. Veterinary drugs in particular can pose a real risk to human health if their residues are allowed to enter the ...
