Metal oxide nanoparticles are one of the most important categories of nanomaterials. Increasing use of metal oxide nanoparticles necessitates an improved understanding of their potential impact on human health. We demonstrated that silica(SiO2) coated magnetic transitional metal oxides (α‐Fe2O3, NiO...

Briefly, metal nanoparticles were washed and re-dispersed in deionized water before being combined into a pre-hydrolysed MPTMS in DI water. Ammonia was added as catalyst. While growth was easily scalable, the growth rate of the silica shell is controllable to 25, 11.7 and 10 nm/h. during ...
The antibacterial activity of the nanoparticles, Ag(28)@mSiO2, Ag(51)@mSiO2, Au@mSiO2and Ag(28)@mSiO2-NH2,was assessed using the broth microdilution method in 96-well microplates following metal concentration into the nanoparticles ranging from 0.1 to 78 µg/mL. Each well was inoculated ...
In this work, gold nanoparticles coated with a fluorescently labelled (rhodamine B) silica shell are presented as fiducial markers for correlative light and electron microscopy (CLEM). The synthesis of the particles is optimized to obtain homogeneous, spherical core-shell particles of arbitrary size....
