Abstract

A nanopore based sequencing system includes a plurality of nanopore sensors. Each nanopore sensor has a portion for receiving a fluid. The nanopore based sequencing system includes a fluid chamber configured to guide the fluid over the plurality of nanopore sensors and an inlet configured to deliver the fluid into the fluid chamber. At least a portion of the fluid chamber is made of a material that has been molded around at least a portion of an electrode.
