Abstract

Engineering nanoparticles in complex matrices.

Highlights

  • Labelling of consumer products containing engineered nanoparticles (ENPs) will be a future legislative requirement in the EU (“EU recommendation on the de nition of nanomaterials”, 2011/696/EU) and in many other countries which develop regulatory approaches for nanomaterials

  • From the regulatory point of view the analytical methodology has to provide size and concentration data of the primary ENPs added to the matrix of interest

  • The developed method must be able to extract the particles without introducing artefacts by the sample preparation procedure, and be independent of any ageing of the ENPs in the complex matrix

Summary

Introduction

Labelling of consumer products containing engineered nanoparticles (ENPs) will be a future legislative requirement in the EU (“EU recommendation on the de nition of nanomaterials”, 2011/696/EU) and in many other countries which develop regulatory approaches for nanomaterials. Analytical methods to detect, characterize, and quantify these ENPs will be. The ENPs in consumer products such as personal care products or foodstuffs are usually suspended or embedded in complex matrices containing particles of sizes and/or compositions similar to the ENPs which shall be quanti ed. Interactions between the matrix components and the ENPs and/or the lack of speci city in measurement techniques prohibit the direct use of available sizing techniques such as nanoparticle tracking analysis (NTA). In order to overcome this problem, von der Kammer et al.[3] suggested using a stepwise procedure (including several preparative and analytical steps) to obtain the 1286 | J.
