Multiple bulk acoustic wave (BAW) resonator structures are arranged along opposing surfaces of a fluidic passage arranged to receive a fluid. At least one resonator structure may be overlaid with functionalization (e.g., specific binding or non-specific binding) material to bind one or more analytes contained in the fluid. Combinations of BAW resonators providing dominant shear response for detection, and providing dominant longitudinal response for mixing or analyte movement, may be provided on one or more surfaces bounding a fluidic passage. Embodiments may reduce the footprint of multi-resonator fluidic device, enhance analyte binding rate, and/or enhance mixing of sample constituents. |
