(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.

Self-assembled monolayer (SAM) of APTES can be used to improve the adhesion of graphene flakes and SiO 2 to enable better contact with the metal electrodes. These electrodes may be used as electro-responsive tools for bio-sensing applications. It can be used to functionalize silane diazirine for fiber optic biosensor application.

Among all organosilanes, APTES is the most used silane molecule to functionalize oxide surfaces [5, 6, 7, 8, 9, 10, 11]. Oxide surfaces are surfaces that have hydroxyl groups (-OH) bearing high surface energy that can rapidly interact and form a covalent bond …

Thermo Scientific Pierce APTS (3-aminopropyltriethoxysilane) is a silylation reagent for coating glass and silica surfaces to add primary amines, which can be used to crosslink and immobilize proteins and other molecules.

APTES is transported from the production site as the parent silane to processors/formulators. Generally, APTES is used by the processor/formulator as an adhesion promoter with use levels <1%. In some applications, APTES is used as a crosslinker; these use levels are higher and can approach 3 to 5 %.

Feb 1, 2012 · The use of the coupling agent, 3-aminopropyltriethoxysilane (APTES), in the silanization reaction with silanol-terminated silicon is an important surface modification reaction.

Intra-molecular catalysis by the amine functionality is found to be important for both silanizaton and hydrolysis. The primary amine group in the G1 silanes (APTES and APTMS) can readily catalyze siloxane bond formation and hydrolysis to render their …

Oct 22, 2008 · Parameters important to the self-assembly of 3-(aminopropyl)triethoxysilane (APTES) on chemically grown silicon oxide (SiO 2) to form an aminopropyl silane (APS) film have been investigated using in situ infrared (IR) absorption spectroscopy.

Jan 27, 2025 · (3-Aminopropyl)tiethoxysilane (APTES) is used as an amino-silane which is mainly used as a dispersant. APTES attaches an amino group to the functional silane for bio-conjugation. Flammability and Explosibility

Dec 9, 2020 · Silanes were previously considered to be unable to chemically condition zirconia to bond with resin. Inclusion of APTES- or MPTS-conditioned nanozirconia fillers can improve the mechanical properties of Bis-GMA-based resin composites without obvious cytotoxicity in …
