We present a dextran modified silicon microring resonator sensor for high density antibody immobilization. An array of sensors consisting of three sensor rings and a reference ring was fabricated and its surface sensitivity and the limit of detection were obtained using polyelectrolyte multilayers. The mass sensitivity and the limit of detection of the fabricated sensor ring are 0.35 nm/ng mm a...

Tyrosinase (TYR) was covalently immobilized onto amino-functionalized carbon felt (CF) surface via glutaraldehyde (GA). Prior to the TYR-immobilization, primary amino group was introduced to the CF surface by treatment with 3-aminopropyltriethoxysilane (APTES). The resulting TYR-immobilized CF was used as a working electrode unit of an electrochemical flow-through detector for monoand di-phenol...

We have used magnetic alternating current mode atomic force microscopy (MAC-AFM) to investigate the formation of supported phospholipid bilayers (SPB) by the method of vesicle fusion. The systems studied were dioleoylphosphatidylcholine (DOPC) on mica and mica modified with 3-aminopropyl-triethoxy-silane (APTES), and DOPC vesicles with gramicidin incorporated on mica and APTES-modified mica. Th...

Chitosan was recently indicated to enhance osteogenesis, improve wound healing but to activate the coagulation and the complement systems. In the present study approximately 10 nm thick chitosan film were prepared on aminopropyltriethoxysilane (APTES) coated silicon. The surfaces were incubated in serum or plasma and subsequently in antibodies towards key complement and contact activation of co...

Abstract Waste tire rubber is commonly recycled by blending with other polymers. However, the mechanical properties of these blends were poor due to lack adhesion between matrix and waste rubber. In this research, use electron beam irradiation (3-Aminopropyl)triethoxy silane (APTES) on enhancing performance 50 wt% reclaimed (RTR) blend poly(ethylene-co-vinyl acetate) (EVA) was investigated. Pre...

Nb 2 CT x MXene oxidation is stopped using APTES functionalization. Amino groups help in sensing acidic NO gas.

in this work we synthesized of mesoporous silica nanoparticles and functionalized with 3-aminopropyltriethoxysilane to improve the loading and release of ibuprofen bonded to 3-aminopropyltriethoxysilane. sample were characterized by fourier transform infrared spectroscopy, scanning electron microscopy , x-ray diffraction, and ultraviolet-visible. the fourier transform infrared spectroscopy resu...

Amino-functionalized SBA-15 type mesoporous silicas having unique hexagonal platelet morphologies with short channels (100-300 nm) running parallel to the thickness of the nanostructured hexagonal platelet type morphologies have been directly synthesized by co-condensation of aminopropyltriethoxysilane (APTES) and sodium metasilicate as a silica source in the presence of Pluronic P123 triblock ...

Silicon photonic devices with either silicon or nitride waveguides have increasingly been used in many applications besides communications, especially as sensors label-free biosensing, where guided light signals are affected by biorecognition molecules immobilized on the surface. The coating of protein (i.e., bioreceptors) biochemical process waveguide surface is a crucial step creating functio...
