Abstract

Silica nanoparticle (SiO2-NPs) are widely used in biomedical applications. Herein, size-controlled nonporous SiO2-NPs were synthesized through the sol-gel process. Calcium (Ca), Zinc (Zn), Nickel (Ni), and Iron (Fe) were successfully incorporated into the SiO2-NPs through calcination process at 680 ฐC for 3 hours. SEM results show high homogeneity of spherical SiO2-NPs with a diameter of 120-140 nm. The surface morphology of doped SiO2-NPs was altered due to the formation of some deposits. EDS spectra confirmed that Ca, Zn, Fe, and Ni were successfully incorporated into SiO2-NPs with not all of the nominal ratio. Atomic % of doped ions increased as the nominal ratio increased from one to two. ฉ 2019 IEEE.
