Acoustofluidics

Acoustic Waves Direct Particles in Microchannels

March 4, 2018

Drug development, artificial tissue design, and the study of intercellular communication are just some of the applications that rely on the precise control of particles or cells in microfluidic devices. By manipulating the fluid motion, [more...]

The 14th Conference on Acoustofluidics

April 28, 2017

This focused meeting is being held outside the EU for the first time in its history, and is dedicated to exploring the science, engineering, and use of micro- to nanoscale acoustofluidics. Topics of interest: Nanoscale acoustofluidics [more...]

A Sound Device Corrals Bacteria in Blood Within Microfluidic Devices

July 14, 2016

When a patient develops sepsis, a potentially fatal inflammatory response to an infection, doctors race to identify what bacterial strain is to blame so they can deliver the best antibiotic. This hunt can take days, however, which can be [more...]

Acoustic Field Identifies Cancer Cells in Blood

May 28, 2016

Researchers at Lund University in Sweden and the Massachusetts Institute of Technology in the United States have developed a method to analyze and separate cells from the blood. Ultimately, the method, which goes under the name [more...]

Particles Move to the Beat of a Microfluidic Drum

May 9, 2016

A thin vibrating plate can organize microscopic particles within a liquid into different patterns, an effect like that observed in 18th century studies of musical instruments. Figure 1: (Top) When dark particles are placed on the back of a [more...]

Thousand-Fold Volumetric Concentration of Live Cells with a Recirculating Acoustofluidic Device

August 2, 2015

The ability to concentrate cells from dilute samples into smaller volumes is an essential process step for most biological assays. Volumetric concentration is typically achieved via centrifugation, but this technique is not well suited for [more...]

Acoustofluidic control of bubble size in microfluidic flow-focusing configuration

December 14, 2014

This paper reports a method to control the bubble size generated in a microfluidic flow-focusing configuration. With an ultrasonic transducer, we induce acoustic streaming using a forward moving, oscillating gas-liquid interface. The [more...]
