Nanoparticle Analysis
Detecting and Characterizing Engineered and Incidental Nanomaterials
Nanoparticles, whether engineered (such as gold nanoparticles, carbon nanotubes, or titanium dioxide) or incidental (produced during industrial processes), present opportunities and challenges for industry and public health. Their extremely small size, unique properties, and potential toxicity make them difficult to monitor and regulate.
Workplace exposures to airborne nanoparticles, as well as contamination in consumer products, dust, bulk materials, and water, are areas of growing concern for regulators, researchers, and manufacturers. Due to their size—often below 100 nanometers—conventional microscopy techniques are insufficient for reliable detection. This creates a need for specialized analytical methods that can detect, measure, and characterize nanoparticles with high precision.
