Claim 10:
11. A method of forming a sensor with a droplet retaining structure comprising:
forming a retaining structure at least partially around a target surface of a substrate, the retaining structure having a height extending in a direction orthogonal to the target surface and a width extending in a direction parallel to the target surface;
disposing a resonating structure on the target surface of the substrate
disposing an insulating layer on the resonating structure; and
disposing a droplet of functionalized material on the resonating structure and the target surface,
wherein a portion of the target surface between the resonating structure and the retaining structure has a width that allows for full coverage of the resonating structure with the droplet of functionalized material such that the droplet of functionalized material auto-aligns with the resonating structure and is prevented from moving, and
wherein the insulating layer is configured to couple to the functionalized material in the droplet.
