Chelating agents as coating molecules for iron oxide nanoparticles

Heinrich Hofmann, Josefina Adriana Maria Bastiaansen, Marijana Mionic Ebersold, Débora Bonvin

Due to their high chemical affinity towards metal ions, chelating agents (CAs) have been used for decades for water purification, but also for protection against metal intoxication and in nanomedicine as linking molecules at the surface of nanoparticles. H ...

Effects of coating spherical iron oxide nanoparticles

Tao Li

We investigate the effect of several coatings applied in biomedical applications to iron oxide nanoparticles on the size, structure and composition of the particles. The four structural techniques employed - TEM, DLS, VSM, SAXS and EXAFS - show no signific ...

Optimisation of aqueous synthesis of iron oxide nanoparticles for biomedical applications

Heinrich Hofmann, Marijana Mionic Ebersold, Débora Bonvin

Iron oxide nanoparticles (IONPs) were prepared via aqueous synthesis which combines alkaline co-precipitation (CP) of ferric and ferrous precursors with mild hydrothermal (HT) treatment without cupping agents (CA). In this novel synthesis route, CP + HT, w ...

Hydrophobization of silver nanoparticles through surface-initiated atom transfer radical polymerization

Heinrich Hofmann, Frank Nüesch, Jose Enrico Quijano Quinsaat

This work describes the synthesis of poly(methyl methacrylate) (PMMA)-coated Ag@SiO2 core-shell particles by conducting a Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP). Silver nanoparticles (AgNPs) were first prepared by the polyol synth ...
