Embodiments of the disclosure provide various nanogap sensor designs (e.g., horizontal nanogap sensors, vertical nanogap sensors, arrays of multiple nanogap sensors, various arrangements for making electrical connections to the electrodes of nanogap sensors, etc.), as well as various methods which may be used to fabricate at least some of the proposed sensors. The nanogap sensors proposed herein may operate as molecular sensors to help identify chemical species through electrical measurements using at least a pair of electrodes separated by a nanogap.

Designs and fabrication of nanogap sensors

A microfabricated thermal platform can be formed over a substrate, such as a silicon wafer, that may form part of the platform. The substrate is coated in a thermally-insulating material, which may be an organic polymer such, as polyimide or SUS. The surface of the thermally-insulating material may include an arrangement of one or more thermal sites, with each site having a reaction plate (or thermal plate) over which chemical reactions may occur. A heating element may be positioned beneath each reaction plate. A fluidic medium, such as a liquid or a gas, may be disposed over the thermal sites. One application is in chemical and biological reactions. In such reactions, the fluidic medium may be an aqueous solution which comprises reagents for those reactions. The fluidic medium may be an ionically conducting fluid, organic solution or a gas. Precise temperature control enables the correct reactions.
