Synthetic amorphous silica is a common food additive and a popular cosmetic ingredient.
Mesoporous silica particles are also widely studied for their potential use in drug delivery …

Sulfate radicals, SO4•-, were generated using flash photolysis of aqueous S2O82-solutions
and the reactions of the inorganic radicals with the surface of suspended silica nanoparticles …

Publisher Summary In this chapter, an overview of the toxicity of silica-based nanomaterials
is presented. Porous materials, such as crystalline, microporous zeolites, and mesoporous …

We have developed structure/toxicity relationships for amorphous silica nanoparticles (NPs)
synthesized through low-temperature colloidal (eg, Stöber silica) or high-temperature …

Introduction of disulfide bridges within silica nanoparticles to control their intra-cellular
degradation - Chemical Communications (RSC Publishing) DOI:10.1039/C3CC41062E Royal …

“Vitreous silica” is a particular form of amorphous silica, much neglected in experimental
studies on silica toxicity. In spite of the incorrect term “quartz glass”, often employed, this …

Samples with varied amount of surface trimethylsilyl groups were obtained via gas-phase
chemical modification of silica nanoparticles. The biocompatibility tests conducted in …

Amorphous silicas, opposite to crystalline polymorphs, have been regarded so far as
nonpathogenic, but few studies have addressed the toxicity of the wide array of amorphous …

The interaction of an H2O molecule with cluster models of fractured silica surfaces was
studied by means of quantum mechanical calculations. Two clusters representing homolytic …

Synthetic amorphous silica (SAS), in the form of pyrogenic (fumed), precipitated, gel or
colloidal SAS, has been used in a wide variety of industrial and consumer applications …
