Abstract
A microfluidic device for sorting biological objects includes a microfluidic chip including a planar substrate having first and second planar surfaces, the planar substrate including first and second networks of channels recessed respectively from the first and second planar surfaces and fluidically connected by way of at least a through-hole in the planar substrate; a first lid attached to the first planar surface of the planar substrate and substantially covering the first network of channels; and a second lid attached to the second planar surface of the planar substrate and substantially covering the second network of channels; and one or more piezoelectric transducers attached to the first lid and/or the second lid and configured to generate first and second acoustic standing waves in a first linear channel of the first network of channels and a second linear channel of the second network of channels, respectively.
