A new, simple, and “green” method was developed for the surface modification of 20nm
diameter Stöber silica particles with 3-aminopropyl (diethoxy) methylsilane in ethanol. The …

Surface modification of silica nanoparticles synthesized by the sol–gel process was
performed using coupling agents, 3-(trimethoxysilyl) propyl methacrylate (MSMA) and/or …

Stöber silica particles having diameters of ca. 100 and ca. 200 nm were prepared and
silylated using trimethylsilyl N, N-dimethylcarbamate, achieving a range of surface coverage …

In this study, surface functionalized silica nanoparticles were prepared through a continuous
two-step sol–gel process. After the TEOS-derived silica particles were synthesized, silane …

Modified silicas were obtained by precipitation from aqueous solutions of sodium
metasilicate and sulphuric acid. For the modification, silane coupling agents with various …

The synthesis of colloidal SiO2 nanoparticles was achieved via the base-catalyzed
hydrolysis and polycondensation of tetraethyl orthosilicate (TEOS) in an alcoholic medium …

We present a general and reproducible one-pot synthesis method to prepare spherical silica
nanoparticles surface-modified with different functional groups directly from tetraethyl …

Quantification of the extent of functionalization on silica nanoparticle surface is crucial in a
variety of applications. This work aims to evaluate particle properties and extent of …

In this study we explore the preparation of 3-mercaptopropyl-, vinyl-and 3-aminopropyl-
functionalized silica monodisperse nanoparticles by direct synthesis (one-pot synthesis') in …

Modified nanosilica powder was prepared with a sol-gel method using a tetraethoxysilane
(TEOS) and γ-amino propyltriethoxysilane (APTES) mixture as the starting materials and …
