General description

(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 97% assay grade is optimized to provide a high density of reactive methoxy groups, ensuring rapid, robust silanization for applications where maximum surface coverage and strong covalent anchoring are required in short reaction windows.

Application

形成玻璃的氨基丙基衍生物，一种用于亲和色谱的吸附剂。用于制备适合用于各种免疫组化和原位杂交过程的带正电荷的玻片。 最近，（3-氨基丙基）三乙氧基硅烷已用于制备具有最小聚集和与生物分子最小非特异性结合的染料掺杂二氧化硅纳米粒子。
