Abstract
A system and method for diagnosing infectious disease using integrated surface acoustic wave sensor technology includes an efficient, low-cost integrated surface acoustic wave (SAW) or bulk acoustic biosensor-based system for point-of-care diagnostics. The SAW or bulk acoustic biosensor, sample receiving portions and interface portions of the system are configured on a disposable cartridge.
Claims29
An integrated acoustic wave biosensor system, comprising,
- a disposable cartridge component, which includes,
- a cassette including:
- a radiofrequency (RF) port configured to receive an RF signal;
- a well for the addition of a sample in a fluid;
- an integrated acoustic wave biosensor, wherein the integrated acoustic wave biosensor includes:
- a piezoelectric base;
- at least one metal coated channel;
- a coded reflector system;
- at least one sensor;
- at least one set of interdigital transducers (IDTs);
- and
- at least two contact pads;
- a galvanic connection assembly coupled to the integrated biosensor;
- and
- a sealing device configured to separate the fluid from the integrated acoustic wave biosensor;
- wherein, the integrated acoustic wave biosensor is activated an RF source.
