The present study deals with the synthesis andfunctionalization of mesoporous silica nanoparticles as drug delivery platforms. SBA-15 nanorods with high surface area (1010 m2g-1) were functionalized by post grafting method using 3-mercaptopropyl trimethoxysilane (MPTS). The parent and thiol-functionalized SBA-15 nanorods were used as nanocarriers for an anticancer drug (gemcitabine). The charac...

Functionalization of carbon nanotube (CNT) was performed, during preparation of Fischer–Tropsch synthesis (FTS) via cobalt nanocatalysts, to modify the surface properties of CNT support. Common and functionalized CNT supported cobalt nanocatalysts were prepared using impregnation wetness method with cobalt loading of 15 wt.%. The catalysts were characterized by Brunauer–Emmett–Teller (BET), Fou...

In this study, Santa Barbara Amorphous (SBA-15) mesoporous silica has been functionalized with aminopropyl groups that were converted to propargyl-bearing moieties through the reaction with propargyl bromide. The material then underwent an efficient Cu(I)-catalyzed azide alkyne click reaction with sodium azide in order to obtain the corresponding triazole products. The covalent modification of ...

Surface active amide-functionalized ionic liquids (ILs) consisting of a long alkyl chain (C6C14) connected to a polar head group (methylimidazolium or pyridinium cation) via an amide functional group were synthesized and their thermal stability, micellar properties and antimicrobial activity in aqueous solution investigated. The incorporation of an amide group increased the thermal stability of...

The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indicate that silica has been successfully coated on the surface of Fe3O4 and 3-aminopropyl tri methoxysilane compound have been grafted to the surface of silica-coated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic spi...

Physicochemical analyses of Au nanoparticle monolayer formation on a glass surface functionalized with 3-aminopropyltrimethoxysilane (APTMS) and ethyltrimethoxysilane (ETMS) were performed for fabricating a nanoarchitecture of metal nanoparticles using self-assembly. The Au nanoparticle surface density on the functionalized glass surface correlated linearly with the optical response because of ...
