High Throughput Acoustic Particle Separation

Tech ID: T-017364

Technology Description:

Methods and devices used for acoustophoresis of biologics have been developed and allow for more than 10,000 fold throughput than existing acoustophoretic devices.

Applications:

1. Isolation of cells in low abundance (immune cells, circulating tumor cells) from whole blood at the point-of-care. Acoustophoretic separation offers excellent biocompatibility and requires no modification of cells or the culture media. This technique can be easily integrated in microfluidic systems or on microfluidic chips. Below: A shows the high-throughput acoustic particle separation device. B details separation of large cells (blue) from RBCs (red) and platelets (yellow). C shows another possible separation scheme for whole blood.

2. Acoustically-confined microcarrier particles that can aid in automated synthesis and purification of modified biologics including antibody conjugates. The microbeads absorb antibodies and provide a solid support for manipulations and conjugation reactions. Beads can be efficiently separated from the reaction mixture using acoustophoresis.

Stage of Development:

Prototypes for acoustic separation are being built and tested. Proof of principle tests for the microcarrier particles on a microchip have been successful. The beads absorbed antibody (B) and were moved using the acoustic field (C), conjugated dyes were added to the antibodies (D), and then cleaved off (E).
