(3-aminopropil)trietoxisilano

(3-Aminopropyl)triethoxysilane (APTES) is a premium, high-purity aminosilane used to deposit stable Self-Assembled Monolayers (SAMs) on silica, metal oxides, and graphene. Its triethoxy structure allows for slower, more controlled hydrolysis compared to methoxysilanes, facilitating the formation of uniform, reproducible molecular layers. Critically for life science research, APTES releases ethanol rather than methanol during silanization, making it the preferred reagent for functionalizing surfaces intended for live-cell interfaces and clinical diagnostics. This 99% high-purity grade is engineered to provide a high density of reactive ethoxy groups for robust covalent anchoring while eliminating the trace impurities that act as charge traps or non-specific binding sites, thereby preventing the critical performance failures in OFETs and nanosensors that standard-grade silanes often cause.

Forma derivados aminopropílicos del vidrio, un adsorbente para la cromatografía de afinidad. Se utiliza para preparar portaobjetos con carga positiva adecuados para emplear en varios procedimientos de inmunohistoquímica y de hibridación in situ. Recientemente, se ha utilizado el (3-aminopropil)trietoxisilano para preparar nanopartículas de sílice dopadas con colorante con agregación mínima y mínima unión inespecífica con biomoléculas.
