Towards long-term colloidal stability of silica-based nanocarriers for hydrophobic molecules: beyond the Stöber method.
نویسندگان
چکیده
The highly uniform micro- and mesoporous SiO(2) nanoparticles (40-70 nm) are hierarchically functionalized with antagonistic groups: hydrophobic (phenyl) on the internal pores and hydrophilic (methyl-phosphonate) on the external surface. Considering the large hydrophobic internal coating and the long-term colloidal stability, these systems are suitable nanocarriers by using the host-guest approach.

Multi-step Coating of Monodisperse Silica Spheres by Titania Nanoparticles Base on Electrostatic Attraction Strategy
TiO2-SiO2 core-shell particles include of monodisperse silica core and nanostructured titania shell were synthesized by a multi-step coating process. The monodisperse silica spheres were synthesized by Stöber method and titania shell was obtained of a colloidal sol prepared by a hydrolysis–condensation reaction. The titania sol was deposited on monodisperse silica spheres by a multi-step coatin...

Abstract Uniform colloidal monodispersed silica nanoparticles were synthesized via stöber method using ammonia as a basic catalyst. Field Emission Scanning Electron Microscope (FESEM) was confirmed the homogeneous nanospheres. The decrease of TEOS concentration (0.067 to 0.012 mol L-1) and an increase of H2O concentration (3 to 14 mol L-1) at 14 mol L-1 NH3 fixed accelerated the rate of h...
متن کاملFacile and economic method for preparation of nano-colloidal Silica with controlled size and stability
This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...
