1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) alone, and in combination with N-hydroxysuccinimide (NHS) or sulfoNHS were employed for crosslinking anti-human fetuin A (HFA) antibodies on 3-aminopropyltriethoxysilane (APTES)-functionalized surface plasmon resonance (SPR) gold chip and 96-well microtiter plate. The SPR immunoassay and sandwich enzyme linked immunosorbent immunoassay (ELISA...

This work investigated for the first time role of adsorption in photocatalytic degradation methylene blue and Orange II dyes presence 3-aminopropyltriethoxysilane (APTES)-modified TiO2 nanomaterials. It has been demonstrated that decrease a detrimental effect on activity. APTES/TiO2 photocatalysts were successfully prepared by solvothermal modification pressure autoclave, followed heat treatmen...

We measure silane density and Sulfo-EMCS cross-linker coupling efficiency on aminosilane films by high-resolution X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) measurements. We then characterize DNA immobilization and hybridization on these films by (32)P-radiometry. We find that the silane film structure controls the efficiency of the subsequent steps toward DNA hybr...

Conductometric sensors have been fabricated by applying imprinted polymers as receptors for monitoring engine oil quality. Titania and silica layers are synthesized via the sol-gel technique and used as recognition materials for acidic components present in used lubricating oil. Thin-film gold electrodes forming an interdigitated structure are used as transducers to measure the conductance of p...

A series of aminopropyl-functionalized silica nanoparticles were prepared through a basic two step sol-gel process in water. Prior to being aminopropyl-functionalized, silica particles with an average diameter of 549 nm were prepared from tetraethyl orthosilicate (TEOS), using a Stöber method. In a second step, aminopropyl-silica particles were prepared by silanization with 3-aminopropyltrietho...

Improvements in durable lubrication together with minimized wear are essential for obtaining long-term, functioning metallic joint prostheses. To achieve this objective, CoCr surface was functionalized Graphene Oxide (GO) and characterized by FTIR XPS. alloy subjected to alkalinization order generate high hydroxyl content on the surface. XPS revealed reactive OH groups, enabling intermediate co...

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 ...

To prepare the reduced graphene oxide (RGO) electrode, we first functionalized the glass slide by soaking the glass in 1% aminopropyl triethoxysilane (APTES) in ethanol for 1 hour. We then washed the slide with ethanol. Previously, we tried washing the slide with water but this caused the slide to become opaque. Also, we originally cleaned the slide first with piranha solution, but eliminating ...

Separation of alkyl sulfate ethoxymers is investigated on various high-performance liquid chromatography (HPLC) stationary phases: Acclaim C18 Surfactant, Surfactant C8, and Hypercarb. For a fixed alkyl chain length, ethoxymers are eluted in the order of increasing number of ethoxylated units on Acclaim C18 Surfactant, whereas a reversed elution order is observed on Surfactant C8 and Hypercarb....

Clay-based nanocomposites have been studied for several decades, mainly focusing on clay-polymer nanocomposites. Here, we report on a simple wet chemical method to synthesize clay-APTES-Au (CAAu) nanocomposites, where 3-aminopropyltriethoxysilane (APTES) acts as the linkage. The silane terminal of APTES formed bonds with the clay surface, while the other -NH(2) terminal bonds to gold nanopartic...
