Abstract
In various examples, an apparatus, system, and method for focusing particles within a two-dimensional suspended fluidic flow are described. A fluid is passed through a two-dimensional channel. The fluid contains particles. An acoustic signal is provided through the fluid channel substantially perpendicular to the two-dimensional fluid flow to align the particles. Characteristics of the particles within the flow, including amount and/or distribution, are determined via optical techniques. Other apparatuses, systems, and methods are disclosed.
Claims19
A two-dimensional suspended fluidic system comprising:
- a first surface;
- a second surface located opposite the first surface, the first surface and the second surface defining a width of a two-dimensional fluid channel, the two-dimensional fluid channel having an inlet and an outlet;
- and
- an acoustic focusing device configured to emit standing acoustic waves into a two-dimensional fluid flow within the two-dimensional fluid channel to drive particles within the two-dimensional fluid flow toward a centerline of an axial direction of the two-dimensional fluid channel.
A two-dimensional suspended fluidic system comprising:
- a fluid channel defined by a first surface and a second surface;
- and
- an acoustic focusing device configured to emit acoustic waves into a two-dimensional flow passing through the fluid channel to drive particles within the two-dimensional flow toward a centerline of an axial direction of the two-dimensional flow.
A method for focusing particles within a two-dimensional suspended fluidic flow, the method comprising:
- passing a fluid through a two-dimensional fluid channel, the fluid containing the particles;
- and
- directing an acoustic signal through the two-dimensional fluid channel substantially perpendicular to a two-dimensional fluid flow of the fluid to align the particles by driving particles within the two-dimensional fluid flow toward a centerline of an axial direction of the two-dimensional fluid flow.
