Abstract
Embodiments of the present disclosure provide methods of forming solid state dual pore sensors which may be used for biopolymer sequencing and dual pore sensors formed therefrom. In one embodiment, a method of forming a dual pore sensor includes providing a pattern in a surface of a substrate. Generally, the pattern features two fluid reservoirs separated by a divider wall. The method further includes depositing a layer of sacrificial material into the two fluid reservoirs, depositing a membrane layer, patterning two nanopores through the membrane layer, removing the sacrificial material from the two fluid reservoirs, and patterning one or more fluid ports and a common chamber.
