Devices and methods for use in removing non-specific binding in a bioassay are disclosed. A substrate can be used with input and output transducers to output surface acoustic waves. The surface acoustic waves can be transmitted through a medium. One of the input and output transducers can be formed on the surface of the substrate aligned with an x-axis of the substrate. These input and output transducers can excite a Rayleigh surface acoustic wave through the medium. Another one of the input and output transducers can be formed orthogonal to the x-axis. These input and output transducers can excite a shear wave.
