Abstract

See full text

A fluidic device incorporating at least one BAW resonator structure (e.g., a biosensing device) and a fluidic passage includes one or more features that provide filtration capability. Certain embodiments include at least one group of pillars extending into the fluidic passage which are arranged between an active region of the at least one BAW resonator structure and at least one fluidic port. Individual pillars are separated from one another by inter-pillar spaces that provide redundant fluid flow paths while preventing passage of obstruction media such as particulate matter, cells, and/or bubbles. Certain embodiments provide porous material arranged in fluid communication with at least one fluidic port and configured to filter contents of fluid supplied thereto. Porous material (e.g., porous membranes) may be provided in a cover structure of a fluidic device or within a filtration cartridge.
