Abstract

Methods are provided for making arrays of distinct polymers covalently bonded to the surface of the a solid support. In the subject methods, at least two distinct polymers, e.g. nucleic acids, are contacted with the surface of a solid support under conditions sufficient for the nucleic acids to become covalently bonded to the surface of the solid support through a cycloaddition reaction, e.g. through the reaction of a diene with a dienophile. Also provided are arrays produced by the subject methods, kits comprising the same and methods for using the arrays in analyte detection, e.g. hybridization, assays.
