Green chemical synthesis for well-defined and sharply distributed SiO 2 @Fe x O y particles
Journal of Sol-Gel Science and Technology(2021)
Abstract
Using a non-toxic precursor, we created a green chemical synthesis for colloidal spheres with a core@shell structure having a silica core and an iron oxide shell (SiO 2 @Fe x O y ). Our synthesis pathway enabled an iron oxide shell formation with a 9 ± 6 nm thick shell onto colloidal silica spheres (ca. 700 nm). SiO 2 @Fe x O y particles reduced A549 cell viability and induced DNA damage. SiO 2 @Fe x O y particles showed the potential for removing fluoride from water.
