Abstract
A flow cell includes: a first substrate; a second substrate; a first resin layer disposed over an inner surface of the first substrate; a second resin layer disposed over an inner surface of the second substrate; a first plurality of biological capture sites located at the first resin layer; a second plurality of biological capture sites located at the second resin layer; and a polymer layer interposed between the first resin layer and the second resin layer, such that the first substrate is attached to the second substrate via at least the first resin layer, the polymer layer, and the second resin layer, wherein the polymer layer defines a plurality of microfluidic channels that extend through polymer layer.
