In the conventional APTES-GA technique, we measured the increased thickness at four stages: (i) initial SiO2 layer due to Si surface oxidization of the sample, (ii) APTES layer, (iii) APTES-GA...

Jan 15, 2020 · In addition, biotin was used to demonstrate the efficiency of APTES modified Si 3 N 4 surface using glutaraldehyde (GA) as a coupling agent. The presence of biotin on the surface was visualized by Alexa Flour 488 conjugated streptavidin through fluorescence microscopy.

Dec 27, 2022 · This review provides an overview of APTES deposition methods, categorized into the solution-phase and vapor-phase, and a comprehensive summary and guide for creating stable APTES monolayers on oxide surfaces for biosensing applications.

(3-Aminopropyl)triethoxysilane (APTES) is an aminosilane frequently used in the process of silanization, the functionalization of surfaces with alkoxysilane molecules. It can also be used for covalent attaching of organic films to metal oxides such as silica and titania.

May 18, 2021 · In the conventional APTES-GA technique, we measured the increased thickness at four stages: (i) initial SiO 2 layer due to Si surface oxidization of the sample, (ii) APTES layer, (iii) APTES-GA layers, and (iv) APTES-GA-protein layers.

Subsequently, functionalizing the magnetic nanoparticles with β-cyclodextrin (Fe 3 O 4-APTES-GA-β_CD) led to a further increase in immobilization, rising from 34.74 % to 44.89 %, surpassing both the bare magnetic nanoparticles (Fe 3 O 4) and those functionalized with …

May 15, 2015 · The APTES modified surfaces can directly react with LDH via physical attachment. LDH can be chemically immobilized on those surfaces after incorporation with glutaraldehyde (GA) to obtain aldehyde layers of APTES-GA modified surfaces.

Apr 1, 2022 · Effect of Biased Neighboring Wire on Polysilicon Wire Biosensors with Sensing Membrane of γ-APTES Mixed with Polydimethylsiloxane-Treated Silica Nanoparticles; Modification of silicon nitride surfaces with GOPES and APTES for antibody immobilization: computational and experimental studies

Sep 28, 2016 · Modified hollow glass microsphere (HGM) particles have been prepared by surface treatment. Coupling agents such as γ-aminopropyltriethoxysilane (APTES), di(dioctylpyrophosphato) ethylene titanate (NDZ-311), and glutaraldehyde (GA) were used as modifiers to improve the hydrophobicity of HGM.

Apr 1, 2024 · We report that modifying CNCs with 3-aminopropyl-triethoxysilane (APTES) via a simple, single-pot reaction scheme dramatically improves the hydrolytic stability of CNC films.
