Abstract
This disclosure describes methods and devices that assist in forming biosensors. Specifically, features that align solutions containing molecules to be immobilized on biosensors. A retaining structure may be disposed at least partially around a target surface of a substrate. A resonating structure may be disposed on the target surface. A droplet of functionalized material may be disposed on the resonating structure and the target surface, which may be auto-aligned and retained by the retaining structure on the target surface to consistently cover the resonating structure.
Claims18
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;
- wherein the retaining structure is formed before disposing the resonating structure on the target surface, or the retaining structure is formed during formation of 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.
