Methods for in situ generation of nucleic acid arrays

摘要

Methods of producing nucleic acid arrays using an in situ nucleic acid synthesis protocol are provided, where the in situ nucleic acid synthesis protocol includes a plurality of cycles, each of which includes: (I) a monomer attachment step; and (II) a functional group generation step. A feature of the subject methods is that the functional group generation step is performed by sequentially flowing a plurality of different fluids across the surface of a substrate in a manner such that the surface is not contacted with a with a triple phase interface line. Also provided are the arrays produced using the subject methods, as well as methods for use of the arrays and kits that include the same.
