Recently, quantum dots have been used as molecular probes substituting for conventional organic fluorophores. Quantum dots are stable against photobleaching and have more controllable emission bands, broader absorption spectra, and higher quantum yields. In this study, an array of ZnS-coated CdSe quantum dots on a slide glass has been prepared by photolithographic method. The array pattern was ...

We demonstrate the cultivation of diatom cells on a functionalized mica surface and the preparation of frustules on a mica surface by baking. Diatom cells were successfully grown on a mica surface treated with 3-aminopropyltriethoxysilane. After baking at 400 degrees C for 2 h, frustule structures without the organic components of the diatom cells were successfully observed by scanning electron...

Flavanone was synthesized through the Claisen–Schmidt condensation between benzaldehyde and acetophenone and subsequent intramolecular Michael addition over aminopropyl-functionalized SBA-15 materials. The catalysts with well-ordered hexagonally arranged mesopores were synthesized by one-pot co-condensation of tetraethoxysilane and aminopropyltriethoxysilane using amphiphilic block copolymer as...

We present a technique for hysteresis suppression in single-wall nanotube field effect transistors (SWNT-FETs) using chemical functionalization. We selectively modify the electrode surfaces and the device channel area with self-assembled monolayers (SAMs) of octanethiol and aminopropyltriethoxysilane (APTES), respectively. These can efficiently prevent surface adsorption of water molecules. We ...

Nanoparticles have an enormous potential for development in biomedical applications, such as gene or drug delivery. We developed and characterized aminopropyltriethoxysilane-functionalized silicon dioxide nanoparticles (APTES-SiNPs) for gene therapy. Lipofectamine(®) 2000, a commonly used agent, served as a contrast. We showed that APTES-SiNPs had a gene transfection efficiency almost equal to ...

Multicolor ZnO quantum dots (QDs) were synthesized and further modified with hydrophobic hexadecyltrimethoxysilane (HDS) and then hydrophilic aminopropyltriethoxysilane (APS) bilayers, resulting in amine-functionalized ZnO@HDS@APS nanocomposites with tunable fluorescence from blue to green yellow. Systematic investigations verify that the resulting ZnO@HDS@APS could display extremely high stabi...

Polyfunctional silylureas were synthesized by the interaction of 3-aminopropyltriethoxysilane with isocyanates various structures in an inert aromatic solvent. Commercially available diisocyanates such as isophorone diisocyanate, hexamethylene 2,4-toluene diisocyanate used isocyanates. In this case, freshly distilled toluene was a The obtained compounds confirmed data IR and NMR1H spectroscopy....
