Device for the separation of particles using a bulk acoustic wave field
The disclosure describes a prism containing a microfluidic channel. By coupling bulk acoustic wave generators to opposing sides of the prism, a standing bulk acoustic wave field can be excited in the prism and in the microfluidic channel. Because the microfluidic channel is titled with respect to the nodes of the bulk acoustic wave field, the prism microfluidic channel device can be used to separate microparticles and biological cells by size, compressibility, density, shape, or mass distribution. This technology enables high throughput cell sorting for biotechnology applications such as cancer cell detection.
