Shear horizontal surface acoustic wave (SH-SAW) resonators and arrays thereof

DWPI Title: Biosensor for on-site detection of contagious or harmful pathogens, virus, bacteria, or nucleic acids, comprises piezoelectric substrate comprising top surface, and electrode region disposed on top surface of piezoelectric substrate
Abstract: The present application relates to a biosensor that employs an acoustic cavity to store mechanical energy. In particular examples, the biosensor includes an electrode region and one or more reflector regions to form the acoustic cavity, as well as a functionalized active area disposed in proximity to the cavity. Methods of making and using such biosensors are also described herein.
Use: Biosensor used for on-site detection of contagious or harmful pathogens, virus, bacteria, nucleic acids, DNA, RNA, proteins, or biomarkers.
Advantage: The biosensor has high sensitivity and specificity with minimal preparation of test sample.
Novelty: Biosensor comprises a piezoelectric substrate (110) comprising a top surface, an electrode region disposed on the top surface of the piezoelectric substrate, one or more reflector regions, a guide layer (120), and a functionalized active area. The electrode region is configured to launch a shear horizontal surface acoustic wave and to detect the acoustic wave transmitted through the substrate.
