Flow Cell Array and Uses Thereof

Abstract

Apparatus and methods for using a flow cell array are provided herein. An apparatus includes an array comprising one or more pixels, wherein each of the one or more pixels comprises multiple reaction sites openings; a first set of one or more sub-surface channels, wherein each of the multiple reaction site openings is connected to a sub-surface channel from the first set of one or more sub-surface channels; a second set of two or more sub-surface channels; and multiple vias connecting each channel from the first set of one or more sub-surface channels to (i) a first sub-surface channel from the second set of two or more sub-surface channels and (ii) a second sub-surface channel from the second set of two or more sub-surface channels.
