    摘要: A substrate, which that is capable of attaching biomolecules, and a method for preparing the substrate are provided. The substrate has a reactive surface that can covalently attach a polymer coating containing functional groups, which can reduce nonspecific binding of biomolecules to the surface for a biological array. Optionally, at least a portion of the substrate may be coated with an intermediate tie layer, which enhances the covalent bonding between the polymer coating with the underlying substrate. The present invention also pertains to a method that uses electrostatic blocking agents to reduce non-specific binding of proteins to a substrate, especially anhydride-modified surfaces.
