Devices comprising functionalized materials, and embodiments of a method for making and using such devices, are disclosed. Exemplary devices include ophthalmic devices, nanoparticles, quartz crystal microbalances, microarrays, and nanocomposites. In particular embodiments, device surfaces are modified with monomers and/or polymers, typically carbohydrate monomers and/or polymers. Embodiments of a method for making and using such devices are disclosed. Monomers and/or polymers are covalently bonded to surfaces using functionalized perhalophenylazides. In some embodiments, device surfaces are functionalized with a perhalophenylazide. One or more monomers and/or polymers subsequently are covalently bonded to the device surface using the perhalophenylazide. In other embodiments, monomers and/or polymers are derivatized with a functionalized perhalophenylazide. The derivatized monomers and/or polymers then are covalently bonded to the device surface using the perhalophenylazide. In some embodiments, graphite is functionalized with perhalophenylazide to produce a functionalized graphene sheet. In other embodiments, graphene sheets are covalently attached to functionalized substrates.
本发明公开了包括功能化材料的装置以及制备和使用这种装置的方法的实施例。示例装置包括眼科装置、纳米颗粒、石英晶体微天平、微阵列和纳米复合材料。在特定的实施例中,装置表面使用单体和/或聚合物进行修饰,通常是碳水化合物单体和/或聚合物。本发明还公开了制备和使用这种装置的方法的实施例。使用功能化的过卤苯基偶氮苯酰胺共价键结合单体和/或聚合物到表面上。在某些实施例中,装置表面被功能化为过卤苯基偶氮苯酰胺。然后使用过卤苯基偶氮苯酰胺将一个或多个单体和/或聚合物共价键结合到装置表面上。在其他实施例中,单体和/或聚合物使用功能化的过卤苯基偶氮苯酰胺衍生。然后使用过卤苯基偶氮苯酰胺将衍生的单体和/或聚合物共价键结合到装置表面上。在某些实施例中,石墨使用过卤苯基偶氮苯酰胺进行功能化,以产生功能化石墨烯薄片。在其他实施例中,石墨烯薄片与功能化基底共价键结合。
