Abstract
Techniques for increasing the lifespan of a nanopore DNA sensing device are disclosed. A related DNA sensing device may be formed by a process comprising forming a first electrode, forming a second electrode, disposing the first electrode and second electrode within an insulator, and disposing a lipid bilayer having a nanopore between the first electrode and second electrode. The forming of the second electrode may comprise forming a silver (Ag) layer, pressing a mold into the Ag layer to form a pattern in the Ag layer, removing the mold from the Ag layer, and exposing the Ag layer to an electrolyte.

A deoxyribonucleic acid (DNA) sensing device formed by a process, the process comprising:
- forming a first electrode;
- forming a second electrode, wherein forming the second electrode comprises:
- forming a silver (Ag) layer;
- pressing a mold into the Ag layer to form a pattern in the Ag layer;
- removing the mold from the Ag layer;
- and
- exposing the Ag layer to an electrolyte;
- disposing the first electrode and the second electrode within an insulator;
- and
- disposing a lipid bilayer having a nanopore between the first electrode and the second electrode.
An electrode formed by a process, the process comprising:
- forming a substantially planar silver (Ag) layer, the layer having a surface area;
- increasing the amount of the surface area of the Ag layer by pressing a mold into the Ag layer to form a pattern in the Ag layer;
- removing the mold from the Ag layer;
- and
- exposing the surface area of the Ag layer to an electrolyte.
