Abstract
The present invention provides methods for creating an array of features on a surface based on content transferred from a plurality of beads to the surface. Nucleic acid content can be transferred using a method including the steps of (a) providing a surface having one or more primer oligonucleotides attached to the surface; (b) providing a pool of beads, wherein beads in the pool have a plurality of templates attached thereto, the plurality comprising multiple copies of a single nucleic acid template sequence; (c) arraying the beads onto the surface by hybridizing the templates to the primer oligonucleotides; and (d) extending the primers to produce copies of the templates attached to the surface.
