Sensing Solution for Airborne Carbon Nanotube Exposure in Workplaces Based on Surface-Enhanced Raman Spectroscopy

Bieri R., Borek-Donten J., Celikkol Zijlstra B., Cattaneo S., Bürgi T., Stat Peel, CH

Today’s advances in man-made nanomaterials pose new and unprecedented health risks, arising especially from airborne, inhalable fiber-shaped nanomaterials, like carbon nanotubes (CNTs). In vivo studies indicate that inhalation of CNTs can cause adverse pulmonary effects [...]

Aerosolization of Carbon Nanotubes for the Development of Reference Air Samples

Cavaliere M.R., Compton S.P., MVA Scientific Consultants, US

Reports on the inhalation risks associated with carbon nanotubes (CNTs) express concern for exposures throughout the lifetime of CNTs and CNT-enabled products. The ability to quantify airborne exposures to workers and consumers will be a [...]

The use of interdigitated microelectrode structures for the detection of exposure to simulated airborne environmental dust

Townsend R.L., Rocks S.A., Dorey R.A., Tearle S., University of Surrey, UK

Particulate matter is ubiquitous in the environment however industrial processes increase the amount released in the air. Here we show the initial development of a novel sensor capable of detecting airborne particulate matter in real [...]

Nanoparticle Characterization and Analysis of Airborne Titanium Dioxide in Powdered Cosmetics

Cavaliere M.R., Compton S.P., MVA Scientific Consultants, US

In this study, several powdered cosmetic products were purchased and evaluated for the presence of TiO2 nanoparticles first by automated particle sizing using scanning electron microscopy (SEM) with chemical typing by energy dispersive spectroscopy (EDS) [...]
