Use of nanomaterials in sample preparation

The article presents recent applications of nanomaterials (metallic, silica and carbon-based) in sample-preparation procedures for sample clean-up and preconcentration of the analytes. Solid-phase extraction, microextraction and filtration techniques reported in 2010-11 are presented and discussed.

► Nanomaterials have shown excellent extraction ability for various compounds.
► Metallic, silica and carbon nanomaterials used for sample clean-up.
► Metallic, silica and carbon nanomaterials used for preconcentration.
► Solid-phase and liquid-liquid extraction can use nanomaterials.
► Microextraction and filtration can use nanomaterials.
