1. A method for surface patterning, the method comprising:
- applying a first set of molecules to a surface of a structure, wherein each of the first set of molecules binds to the surface and lacks a reactive group capable of binding to a nucleo side;
applying electromagnetic radiation (EMR) to predetermined regions of the surface, wherein the EMR comprises a wavelength from about 100 nm to about 300 nm, wherein application of the EMR results in removal of the first set of molecules at the predetermined regions, thereby defining different loci for oligonucleotide extension; and
synthesizing a plurality of oligonucleotides, wherein each oligonucleotide extends from a different locus, and wherein the different loci are at least about 75% uniform when measured by calculating amplitude of signal variation for oligonucleotides extending from each locus divided by total signal intensity following white light illumination using an optical microscope.

20. A method for gene synthesis, the method comprising:
-
providing predetermined sequences for a plurality of oligonucleotides, wherein the plurality of oligonucleotides collectively encode for a plurality of genes; providing a surface for oligonucleotide synthesis; synthesizing the plurality of oligonucleotides from the surface, wherein each oligonucleotide extends from a different locus, and wherein the different loci are at least about 75% uniform when measured by calculating amplitude of signal variation for oligonucleotides extending from each locus divided by total signal intensity following white light illumination using an optical microscope; and assembling the plurality of genes from the plurality of oligonucleotides. - View Dependent Claims (21)
