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 [...]

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 [...]

Flame Synthesis and Coating of Nanostructured Particles in One Step

Teleki A., Buesser B., Heine M., Krumeich F., Akhtar M.K., Pratsinis S.E., ETH Zürich, CH

Coating of flame-made nanostructured particles has been achieved in one step by a scalable aerosol process. Rutile TiO2 particles made by flame spray pyrolysis (FSP) were coated in a single step with SiO2 layers in [...]

Hermetically-Coated Superparamagnetic Fe2O3 Particles with SiO2 Nanofilms

Teleki A., Suter M., Kidambi P.R., Ergeneman O., Krumeich F., Nelson B.J., Pratsinis S.E., ETH Zürich, CH

Magnetic nanoparticles are frequently coated with SiO2 to improve their functionality and bio-compatibility in a range of biomedical and polymer nanocomposite applications. In this paper, a scalable flame aerosol technology is used to produce highly [...]

Sensing of Organic Vapors by Flame-Made TiO2 Nanoparticles

Teleki A., Pratsinis S.E., Kalyanasundaram K., Gouma P.I., ETH Zürich, CH

Nanostructured anatase TiO2 was produced by flame spray pyrolysis (FSP) and tested for sensing of volatile organic compounds and CO at 500 °C. The as-prepared powders were characterized by transmission/scanning electron microscopy, x-ray diffraction and [...]
