Abstract

An example of a flow cell includes a substrate, which includes nano-depressions defined in a surface of the substrate, and interstitial regions separating the nano-depressions. A hydrophobic material layer has a surface that is at least substantially co-planar with the interstitial regions and is positioned to define a hydrophobic barrier around respective sub-sets of the nano-depressions.
