Abstract

A fluidic device includes at least one bulk acoustic wave (BAW) resonator structure with a functionalized active region, and at least one first (inlet) port defined through a cover structure arranged over a fluidic passage containing the active region. At least a portion of the at least one inlet port is registered with the active region, permitting fluid to be introduced in a direction orthogonal to a surface of the active region bearing functionalization material. Such arrangement promotes mixing proximate to a BAW resonator structure surface, thereby reducing analyte stratification, increasing analyte binding rate, and reducing measurement time.

Claims (13)

1 . A fluidic device comprising:

a bulk acoustic wave resonator structure including a top side electrode, a bottom side electrode, and an active region;

wherein a functionalization material is included at the active region;

a fluidic passage including a first port;

wherein the first port is in fluid communication with the active region, and is configured to permit fluid to enter the fluidic passage from above the top side electrode of the bulk acoustic wave resonator structure; and

wherein the fluidic device further comprises a second port, wherein the second port overlaps a portion of the active region.

2 . A fluidic device comprising:

a bulk acoustic wave resonator structure including a top side electrode, a bottom side electrode, and an active region;

wherein a functionalization material is included at the active region;

a fluidic passage having a port;

wherein the port is in fluid communication with the active region;

wherein at least one selected from the group of a self-assembled monolayer SAM), interface layer, and a hermeticity layer is positioned adjacent to the functionalization material; and

wherein the fluidic device further comprises a substrate defining a recess, wherein the active region is aligned with the recess.
