An integrated methodology across the dispersion preparation-characterization-in vitro dosimetry continuum for engineered nanomaterials

Cohen J., DeLoid G., Pirela S., Pyrgiotakis G., Demokritou P., Harvard School of Public Health, US

Evidence continues to grow of the importance of in vitro and in vivo dosimetry in the hazard assessment and ranking of engineered nanomaterials (ENMs). Accurate dose metrics are particularly important for in vitro cellular screening [...]

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 [...]

A novel method for bacteria inactivation using Engineered Water Nanostructures

Pyrgiotakis G., McDevitt J., Yamauchi T., Demokritou P., Harvard School of Public Health, US

Herein we present a novel method for microbial disinfection that utilizes the formation of unique Engineered Water Nanostructures (EWNS) generated via the electrospraying of water. Electropsray is a method widely, used to generate aerosols and [...]
