Provided are functionalized silicon compounds and methods for their synthesis and use. The functionalized silicon compounds include at least one activated silicon group and at least one derivatizable functional group. Exemplary derivatizable functional groups include hydroxyl, amino, carboxyl and thiol, as well as modified forms thereof, such as activated or protected forms. The functionalized silicon compounds may be covalently attached to surfaces to form functionalized surfaces which may be used in a wide range of different applications. In one embodiment, the silicon compounds are attached to the surface of a substrate comprising silica, such as a glass substrate, to provide a functionalized surface on the substrate, to which molecules, including polypeptides and nucleic acids, may be attached. In one embodiment, after covalent attachment of a functionalized silicon compound to the surface of a solid silica substrate to form a functionalized coating on the substrate, an array of nucleic acids may be covalently attached to the substrate. Thus, the method permits the formation of high density arrays of nucleic acids immobilized on a substrate, which may be used, for example, in conducting high volume nucleic acid hybridization assays.
提供了功能化硅化合物及其合成和使用的方法。这些功能化硅化合物包括至少一个活化的硅基团和至少一个可衍生的功能基团。可衍生的功能基团包括羟基、氨基、羧基和硫醇,以及其修饰形式,如活化或保护形式。这些功能化硅化合物可以共价地附着在表面上形成功能化表面,可用于各种不同的应用。在一种实施例中,硅化合物附着在包括二氧化硅的基底表面上,如玻璃基底上,以提供基底上的功能化表面,可附着分子,包括多肽和核酸。在一种实施例中,在将功能化硅化合物共价地附着在固体二氧化硅基底表面上形成基底的功能化涂层后,可以共价地附着一系列核酸到基底上。因此,该方法允许在基底上固定高密度的核酸阵列,可用于进行高容量的核酸杂交试验。
