Abstract: Methods for fabricating functionalized substrate surfaces for use in preparing biomolecular microarrays, such that the substrate surfaces feature a uniform distribution of attachment functionality, functionalized substrates having such uniform distribution of attachment functionality, and microarrays prepared from such functionalized substrates. A plurality of linker groups are coupled to a substrate surface. A plurality of spacer groups including attachment sites for biological receptors are coupled to the linker groups. The linker groups can be coupled to the surface using a gas phase reaction. Spacers can include polyfunctional linear, branched or dendritic structures, such as polyethylene glycols and Starburst™ dendrimers. Attachment sites can be activated for the attachment of biological receptors.
