Publication number: 20130165350Abstract: The present invention provide several methods of derivatizing a surface of a support with one or more linkers thus providing a suitable platform for synthesis of a polymer array, particular a nucleic acid array. Some methods derivatize a surface with a self-assembled monolayer (SAM) of a linker. The SAM confers advantages of hydrolytic stability, broad compatibility with synthesis and detection chemistries, and reduced emergence of latent functional groups during polymer array synthesis. Substrates can also be derivatized with multi-layers of SAMs providing greater hydrolytic stability. Substrates can also be derivatized by synthesizing a linker in situ on the substrate by atom transfer radical polymerization of functional and functional monomers. Appropriate selection of monomers reduces emergence of latent functional groups in subsequent array synthesis.Type: ApplicationFiled: December 22, 2011Publication date: June 27, 2013Applicant: Affymetrix, Inc.Inventors: Robert Kuimelis, Glenn McGall, Dexter Pao, Zihui Chen, Trevor Axelrod
