Abstract

Devices for sorting components (e.g., cells) contained in a liquid sample are provided. In certain aspects, the devices include a magnetic separation device and an acoustic concentrator device fluidically coupled to magnetic separation device. Aspects of the invention further include methods for sorting cells in a liquid sample, and systems, and kits for practicing the subject methods.

Claims (18)

1. A fluidic device for manipulating components in a liquid sample, the device comprising:

a magnetic separator; and

an acoustic concentrator fluidically coupled to the magnetic separator, wherein the acoustic concentrator comprises:

a flow channel comprising an inlet and an outlet, the inlet and outlet defining a fluid flow path therebetween; and

a vibration generator positioned adjacent to the fluid flow path and configured to produce an acoustic field in the fluid flow path.

2. The device according to claim 1 , wherein the acoustic concentrator is fluidically coupled to an output of the magnetic separator.

3. The device according to claim 1 , wherein the liquid sample has a viscosity of about 0.2 cP to about 1.5 cP.

4. The device according to claim 1 , wherein the liquid sample comprises cells.

5. The device according to claim 1 , wherein the device has an output flow rate of about 30 to 100 μL/min.

6. The device according to claim 1 , wherein the magnetic separator comprises a permanent magnet.

7. The device according to claim 1 , wherein the magnetic separator comprises a magnetic field guide.

8. The device according to claim 1 , wherein the vibration generator is a piezoelectric transducer.

9. The device according to claim 8 , wherein the vibration generator comprises lead zirconate titanate.

10. The device according to claim 1 , comprising a processor configured to apply a magnetic field using the magnetic separator.

11. The device according to claim 1 , comprising a processor configured to control the acoustic concentrator.

12. A flow cytometric system comprising:

a flow cytometric sample fluidic subsystem, the flow cytometric sample fluidic subsystem comprising: a magnetic separator; and an acoustic concentrator fluidically coupled to the magnetic separator; and

a flow cytometer fluidically coupled to the output of the flow cytometric sample fluidic subsystem.
