Clinical applications of acoustophoresis in blood based

The Phabian Award - Apotekarsocieteten

Here, using acoustophoresis, we present for the first time a label-free method to achieve continuous background dilution in droplets containing cells with high sample recovery. The system comprises droplet generation, acoustic focusing, droplet splitting, picoinjection, and serpentine mixing on the same chip. Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces. However acoustic tweezers are generally small scale devices which operate in a fluid medium and are less affected by gravity, whereas acoustic levitation is primarily concerned with overcoming gravity.

This wave causes the In addition, the method would allow simultaneous detection of certain antibiotic resistance genes possibly carried by the bacteria in the blood sample. The unique feature of the approach was the integration of acoustophoresis-based sample preparation method with polymerase chain reaction (PCR) based bacterium detection and identification. Acoustophoresis is getting more attention as an effective and gentle non-contact method of manipulating cells and particles in microfluidic systems. A key to a successful assembly of an acoustophoresis system is a proper design of the acoustic resonator where aspects of fabrication techniques, material choice, thickness matching of involved components, as well as strategies of actuation, all 2012-07-07 · The method relies on the assumption that each particle in the suspension undergoes single-particle acoustophoresis.

The rectangular cross-section separation channel (370 ím wide, 125 ím deep) had three inlets: one particle-free medium inlet, located at the beginning of the preparation methods using active and passive particle manipulation techniques for point of care diagnostic applications. The active technique is based on acoustophoresis (acoustic manipulation) while the passive method is based on inertial microfluidics (hydrodynamic manipulation).

On-chip ultrasonic sample preparation for cell based assays

It is the migration of cells or particles with sound. On exposure to an acoustic wave field, radiation force affects particles. This thesis presents studies of microparticle acoustophoresis, a technique for manipulation of particles in microsystems by means of acoustic radiation and streaming forces induced by ultrasound standing waves.

BAW acoustophoresis has Researchers from MIT, Pennsylvania State University, and Carnegie Mellon University have devised a new way to separate cells by exposing them to sound waves Therefore, the acoustophoresis method enables a gentle cell separation based on the intrinsic acoustophysical parameters in a non-contact, non-harmful label-free system. 14, 15. In this study, we investigate whether we can concentrate live cells from a mixed population of live and dead cells using acoustophoresis. “That laid the foundation for the microchipbased, acoustophoresis method which we are now further developing to separate circulating tumor cells from blood. A similar microchip configuration is now also used to study the cardiovascular regulation mechanisms of red blood cells.” Ultrasound sorts cells An acoustophoresis-based microfluidic flow-chip is presented as a novel platform to facilitate analysis of proteins and peptides loosely bound to the surface of beads or cells.
