There is disclosed a method for producing a substrate for making a microarray, the method comprising: at least, a step of forming a monomolecular film having orientated oxysilanyl groups toward an outmost surface on the substrate; and a step of forming a monomolecular film having orientated amino groups toward an outmost surface on the substrate by applying a solution containing a diamine compound to the oxysilanyl groups. There can be provided a method for producing a substrate for making a microarray in which density and orientation of amino groups orientated toward an outmost surface are controllable, and in addition, there is no delamination of a monomolecular film formed on the substrate.
本发明公开了一种制备微阵列基板的方法,该方法包括:至少形成一层单分子膜,该单分子膜在基板表面上具有定向的氧
硅烷基团;并通过在氧
硅烷基团上施加含有二胺化合物的溶液,形成一层单分子膜,该单分子膜在基板表面上具有定向的
氨基团。可以提供一种制备微阵列基板的方法,其中定向朝向表面的
氨基团的密度和取向是可控的,此外,形成在基板上的单分子膜不会剥离。
