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.

A method of making an array of at least two distinct polymeric compounds of differing composition covalently bonded to a surface of a solid support, said method comprising:
- contacting a surface of a solid support having a cycloaddition reactive group and a contact angle ranging from about 20° to 100° with said distinct polymeric compounds under conditions sufficient for said polymeric compounds to covalently bond to said surface by a cycloaddition reaction.
A method of producing an array of at least two distinct nucleic acids that differ by sequence covalently bonded to the surface of a solid support, said method comprising:
- contacting a surface of a solid support having a cycloaddition reactive group and a contact angle ranging from about 20 to 100° with said nucleic acids under conditions sufficient for said nucleic acids to covalently bond to said surface by a Diels-Alder reaction;
- whereby said array of nucleic acids is produced.
A method of producing an array of at least two distinct polydeoxyribonucleotides that differ by sequence covalently bonded to the surface of a solid support, said method comprising:
