Magnetic hybrid nanoparticles for improvements in analytical processes

Autor: Ángel Ríos, Mohammed Zougagh, R.C. Rodríguez Martín-Doimeadios, Francisco Javier Guzmán Bernardo

Magnetic hybrid nanoparticles (MHNPs) are very interesting tools in analytical chemistry because they improve different steps of the analytical process. MHNPs contribute to sample preparation in terms of selectivity and sensitivity. They also simplif

Rapid assessment of silver nanoparticle migration from food containers into food simulants using a qualitative method

Autor: Silvia Avendaño García, R.C. Rodríguez Martín-Doimeadios, Ángel Ríos, Francisco Javier Guzmán Bernardo, Ana I. Corps Ricardo

Publikováno v: Food chemistry. 361

Migration of silver nanoparticles (AgNPs) from food containers (FCs) has been assessed for the first time using a screening method previously validated. Migration was evaluated using water and 3% acetic acid as food simulants (FSs), from 20 to 70 °C
