Biosensors on Surface Acoustic Wave Phononic Band Gap Structures

چکیده
page 156 Abstract: Already proven in a wide array of industrial applications, surface acoustic wave devices (SAWs) also have been demonstrated to hold substantial potential in the biosensor arena. Currently, SAW resonators coated with a biolayer can distinguish specific biomolecules in both liquid and vapor phases. By incorporating periodic perturbations in the design of SAW delay line, we were able to introduce a phononic band gap in the propagation of surface waves. With the coating of a specific biolayer on these band gap structures, we looked at how the phononic crystal affected the detection of molecules. Finally, we will discuss our results and compare them with current acoustic wave biosensors.

Full band gap for surface acoustic waves in a piezoelectric phononic crystal.
A plane-wave-expansion method suited to the analysis of surface-acoustic-wave propagation in two-dimensional piezoelectric phononic crystals is described.
