General description

(3-Aminopropyl) trimethoxysilane (APTMS) is an aminosilane which is used in silanization processes as a silane coupling agent. It functionalizes substrates with alkoxysilane molecules.
(3-Aminopropyl)trimethoxysilane(APTMS) is an amino-silane that is mainly used as a silane coupling agent for the surface modification of a variety of nanomaterials. APTMS based films form a thermally stable layer on different substrates.

Application

APTMS can be multilayered on SiOx substrates by a layer by layer self assembly. APTMS has also been used as a silane coupling agent on silver nanoparticles.
APTMS is used for the synthesis of gold nano-bipyramids which can be used as substrates for C-reactive protein (CRP) antibodies that were detected by localized surface plasmon resonance(LSPR). Mesoporous silica matrix can be incorporated with APTMS for the removal of chromium (Cr) from waste water. It can also be used to silanize magnetic iron oxide nanoparticles(MIONPs) for the separation of cross-linked enzyme aggregations (CLEAs) from the reaction medium. It may be coated on TiO2 to improve the power conversion efficiency (PCE) as a critical parameter to assess the overall performance of heterojunction perovskite solar cells (PSCs).

Packaging

Optically tunable core-shell composite nanorod structures have been prepared by depositing gold onto silica and titania nanorods which have been surface modified with (3-Aminopropyl)trimethoxysilane
