1. A substrate comprising:
- a functionalizable layer;
a UV-cured polymer layer comprising a plurality of micro-scale or nano-scale patterns, or combinations thereof; and
a backing layer;
wherein the micro-scale or nano-scale patterns of the UV-cured polymer layer comprise channels, trenches, wells, posts, or combinations thereof;
wherein the functionalizable layer comprises a reaction product of a functionalizable polymer and a layer of condensed norbornene silane, wherein the functionalizable polymer comprises one or more functional groups selected from the group consisting of azide, optionally substituted alkene, optionally substituted hydrazone, optionally substituted tetrazole, optionally substituted tetrazine and thiol; and
wherein the UV-cured polymer layer comprises at least one photocurable polymer and is free of photoresist.

Abstract
Substrates comprising a functionalizable layer, a polymer layer comprising a plurality of micro-scale or nano-scale patterns, or combinations thereof, and a backing layer and the preparation thereof by using room-temperature UV nano-embossing processes are disclosed. The substrates can be prepared by a roll-to-roll continuous process. The substrates can be used as flow cells, nanofluidic or microfluidic devices for biological molecules analysis.
