Abstract: An apparatus includes a flow cell body, a plurality of electrodes, an imaging assembly, and one or more barrier features. The flow cell body defines one or more flow channels and a plurality of wells defined as recesses in the floor of each flow channel. Each well is fluidically coupled with the corresponding flow channel. The flow cell body further defines interstitial surfaces between adjacent wells. Each well defines a corresponding depth. Each electrode is positioned in a corresponding well of the plurality of wells. The electrodes are to effect writing of polynucleotides in the wells. The imaging assembly is to capture images of polynucleotides written in the wells. The one or more barrier features are positioned in the wells, between the wells, or above the wells. The one or more barrier features contain reactions in each well, reduce diffusion between the wells, or reduce optical cross-talk between the wells.

Abstract: An apparatus includes a flow cell body, a plurality of electrodes, an integrated circuit, and an imaging assembly. The flow cell body defines one or more flow channels and a plurality of wells. Each flow channel is configured to receive a flow of fluid. Each well is fluidically coupled with the corresponding flow channel. Each well is configured to contain at least one polynucleotide. Each electrode is positioned in a corresponding well of the plurality of wells. The electrodes are operable to effect writing of polynucleotides in the corresponding wells. The integrated circuit is operable to drive selective deposition or activation of selected nucleotides to attach to polynucleotides in the wells to thereby generate polynucleotides representing machine-written data in the wells. The imaging assembly is operable to capture images indicative of one or more nucleotides in a polynucleotide.
