Acoustofluidics papers Biomedical Engineering

Acoustophoretic particle focusing is a modern and very attractive method of removing a variety of objects from solutions in a microfluidic channel. The process is applicable to healthcare applications (malignant cell removal), academic research (nanoparticle separation), industrial applications (reclaiming of rare earths) and acoustophoresis ( uncountable ) acoustic levitation; a method for suspending matter in a medium by using acoustic radiation pressure from intense sound waves in the medium quotations . 2015 November 12, “Cancer Cell Analyses at the Single Cell-Level Using Electroactive Microwell Array Device”, in PLOS ONE ‎ [1], DOI: 10.1371/journal.pone.0139980: Grenvall C. et al., Concurrent Isolation of Lymphocytes and Granulocytes Using Prefocused Free Flow Acoustophoresis, Anal Chem, 2015, 87, 5596-5604. Urbansky A. et al., Label-free separation of leukocyte subpopulations using high throughput multiplex acoustophoresis, Lab Chip, 2019, 19, 1406-1416 Technically dynamic acoustic levitation is a form of acoustophoresis, though this term is more commonly associated with small scale acoustic tweezers. Typically sound waves at ultrasonic frequencies are used thus creating no sound audible to humans. This is primarily due to the high intensity of sound required to counteract gravity. Acoustophoresis is a method based on the migration of suspended particles or cells in an acoustic field caused by the acoustic radiation force.

Acoustophoresis

This paper demonstrates, for the first time, acoustophoresis performed in isotropically etched glass chips providing a performance that matches that of the corresponding silicon microdevices. A most fundamental acoustophoresis structure is a straight separation channel with one inlet that ends in a trifurcation. When actuated in a half wavelength, standing wave mode particles will gather in the center of the channel and in combination with the laminar flow, a single band of particles will form (Fig. 3 A).

Zixing Liu Key Laboratory of Modern Acoustics (MOE), School of Physics, Collaborative Innovation Center of Advanced Microstructure, Nanjing University, Nanjing 210093, China. Acoustically induced particle motion, referring to acoustophoresis, is typically implemented by generating a standing acoustic field across a microfluidic channel. Suspended particles exposed to the standing field are subjected to two acoustic effects, which are acoustic radiation force and Stokes drag force from acoustic streaming flow. We present a numerical model for the recently introduced simple and inexpensive micromachined aluminum devices with a polydimethylsiloxane (PDMS) cover for microparticle acoustophoresis.

Despite the fact that experimental studies have been extensively performed to demonstrate this technique for various microfluidic applications, numerical simulation of acoustophoresis driven by surface acoustic waves (SAWs) has still been largely unexplored. Free Flow Acoustophoresis (FFA) can be considered as one of the most efficient approaches for high-throughput separation of microparticles or cells from complex suspensions such as blood samples. 31,173,174 A dedicated review series has been written on the subject.

Enrichment of microparticles in droplets using acoustophoresis

The technology is currently finding increased applications in bioanalytical and clinical applications of cell handling and manipulation. The word "Acoustophoresis" means migration with sound. It consists of two parts, where phoresis means "migration" and acousto where sound waves are the modus operandi of the movement.
