Close-up after acoustic separation of cancer cells from blood cells into separate bins. Left: Cancer cell bin shows a green cancer cell and just a few smaller white blood cells. Right: White blood cell bin shows numerous white blood cells with only a single green cancer cell. The experiment demonstrates that the acoustic system successfully separates the two cell types with near-perfect accuracy.
