Abstract
One example of a flow cell includes a base support and a multi-layer stack positioned over the base support. The multi-layer stack includes a resin layer positioned over the base support; and a hydrophobic layer positioned over the resin layer. A depression is defined in the multi-layer stack through the hydrophobic material and through a portion of the resin.
Claims15
A flow cell, comprising:
- a base support;
- a multi-layer stack positioned over the base support, the multi-layer stack including:
- a resin layer positioned over the base support;
- and
- a hydrophobic layer positioned over the resin layer;
- and
- a depression defined in the multi-layer stack through the hydrophobic material and through a portion of the resin.
4 more elements
A method, comprising:
- defining a depression in a multi-layer stack including a hydrophobic layer over a resin layer by:
- i) etching through a depth of the hydrophobic layer;
- or
- ii) imprinting and etching the hydrophobic layer through a depth of the hydrophobic layer;
- or
- iii) imprinting through a depth of the hydrophobic layer and through a portion of a depth of the resin layer;
- and
- applying a functionalized layer in at least one region of the depression.
5 more elements
A method, comprising:
- applying a sacrificial layer over a first portion of a depression defined in a substrate, whereby a second portion of the depression remains exposed;
- applying a first functionalized layer over the sacrificial layer and over the second portion of the depression;
- removing the sacrificial layer and the first functionalized layer applied thereon, thereby exposing the first portion of the depression;
- applying a second functionalized layer over the second portion of the depression;
- and
- attaching respective primers sets to the first and second functionalized layers.
