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.
