Cytotoxicity of silver nanoparticles

Sotiriou G.A., Pratsinis A., Pratsinis S.E., Leroux J.-C., Pratsinis A., Pratsinis S.E., Particle Technology Laboratory, ETH Zürich, CH
Silver nanoparticles are receiving more and more attention for their plasmonic colors and their antibacterial effects [1]. The addition of a nanothin SiO2 shell minimizes the release of toxic Ag ions and the contact of [...]

Quantifying the origin of nanosilver ions and their antibacterial activity

Sotiriou G.A., Meyer A., Knijnenburg J., Panke S., Pratsinis S.E., Particle Technology Laboratory, ETH Zürich, CH
Nanosilver is prominent in nanotechnology products [1]. Concerns however about leached Ag ions from its surface into aquatic environments have challenged its broad use. The origin of these ions is explored here by conditioning the [...]

Hybrid silica-coated palsmonic-magnetic biomarkers

Sotiriou G.A., Hirt A.M., Lozach P-Y., Teleki A., Krumeich F., Pratsinis S.E., Particle Technology Laboratory, ETH Zürich, CH
In this study, hybrid silica-coated plasmonic-magnetic nanoparticles have been synthesized in one-step by a scalable flame aerosol technology. The effect of the silica in the stability of the nanoparticles, as well as their biocompatibility are [...]

Color tunable nanophosphors

Sotiriou G.A., Schneider M., Pratsinis S.E., Particle Technology Laboratory, ETH Zürich, CH
In this study, yttrium oxide nanophosphors doped with Tb and Eu ions were made by flame aerosol technology. The emission color of these nanophosphors could be precisely tuned from green to red by tuning the [...]

Plasmonic Biosensors with biocompatible nanosilver

Sotiriou G.A., Sannomiya T., Teleki A., Voeroes J., Pratsinis S.E., Particle Technology Laboratory, ETH Zürich, CH
In this study, silica-coated nanosilver particles were made by flame aerosol technology. The effect of the silica coating on the morphology of the particles, as well as their biocompatibility was examined. Finally, the potential of [...]
