Nanotechnology: Characterization of Nanomaterials using Single-Particle ICP-MS

The measurement and characterization of nanoparticles is critical to all aspects of nanotechnology. The widespread application of nanomaterials has inevitably led to their release into the environment, which raises concern about their potential adverse effects on the ecosystems and their impact on health. Complete characterization of nanomaterials is important for interpreting the results of toxicological and human health studies.  Many analytical techniques are available for nanometrology, only some of which can be successfully applied to environmental health studies.  One technique that is proving invaluable for detecting and sizing metallic nanoparticles is SP-ICP-MS. Its combination of elemental specificity, sizing resolution and unmated sensitivity makes it extremely applicable for the characterization of nanoparticles which have been integrated into larger products such as foods, consumer goods, personal care products, and pharmaceuticals.
