General description

(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.

Application

Forms aminopropyl derivative of glass, an adsorbent for affinity chromatography. Used to prepare positively charged slides suitable for use with various immunohistochemical and in situ hybridization procedures. Recently (3-Aminopropyl)triethoxysilane has been used to prepare dye-doped silica nanoparticles with minimal aggregation and minimal nonspecific binding with biomolecules.
Used in a preparation of a series of tenary composite films of polyimide/SiO/polydiphenylsiloxane with good optical transparency.
Self-assembled monolayer (SAM) of APTES can be used to improve the adhesion of graphene flakes and SiO2 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. Hollow microcarriers (HMCs) can be surface modified with APTES which may be used for regenerative medicines and recombinant cells in biopharmaceutical industries.
