A safer-by-design formulation concept for flame-generated engineered nanomaterials

Gass S., Pyrgiotakis G., Cohen J.M., Sotiriou G.A., Pratsinis S.E., Demokritou P., Harvard School of Public Health, US

As more consumers and factory workers become exposed to engineered nanomaterials (ENMs), the question of exposure risks is rapidly gaining importance. Engineering less toxic ENMs that maintain valuable functional properties is therefore crucial to the [...]

A safer formulation concept for flame-generated engineered nanomaterials

Gass S., Pyrgiotakis G., Cohen J.M., Sotiriou G.A., Pratsinis S.E., Demokritou P., Harvard School of Public Health, US

Engineering less toxic ENMs that maintain valuable functional properties is crucial to the sustainability of the nanotech industry. Core-shell nanoparticles are particularly interesting in this regard. They exhibit the surface properties of their shells while [...]

Breath acetone monitoring by portable Si:WO3 gas sensors

Righettoni M., Tricoli A., Gass S., Schmid A., Amann A., Pratsinis S.E., ETH Zürich, CH

Breath analysis has the potential for early stage detection and monitoring of illnesses to drastically reduce the corresponding medical diagnostic costs. In particular, the detection of acetone in the human breath is promising for non-invasive [...]

Portable gas sensor for breath analysis

Righettoni M., Tricoli A., Gass S., Pratsinis S.E., ETH Zürich, CH

The detection of acetone in the human breath is a promising method for the noninvasive diagnosis and monitoring of diabetes. Here, a portable and highly selective acetone-sensor was developed by direct flame synthesis and deposition [...]
