Acoustofluidic dynamic interfacial tensiometry
The Journal of the Acoustical Society of America, 2021The interfacial tension (IFT) of fluids plays an essential role in industrial, biomedical, and synthetic chemistry applications; however, measuring IFT at ultralow volumes is challenging. Here, we report a novel method for sessile drop tensiometry using surface acoustic waves (SAWs).

Working with extremely small fluid samples has been difficult due to evaporation and the dominance of surface and viscous forces. Recent work has demonstrated that manipulation of fluids and their contents at these scales is now possible using MHz-order acoustic waves, not only due to acoustic streaming but other, newly discovered nonlinear ...

Acoustofluidic platforms for particle manipulation
ELECTROPHORESIS, 2021AbstractThere is an increasing interest in acoustics for microfluidic applications. This field, commonly known as acoustofluidics involves the interaction of ultrasonic standing waves with fluids and dispersed microparticles. The combination of microfluidics and the so‐called acoustic standing waves (ASWs) led to the development of integrated systems ...

Acoustofluidics 18: Microscopy for acoustofluidic micro-devices
Lab on a Chip, 2012In this tutorial review in the thematic series "Acoustofluidics", we discuss the implementation and practice of optical microscopy in acoustofluidic micro-devices. Examples are given from imaging of acoustophoretic manipulation of particles and cells in microfluidic channels, but most of the discussion is applicable to imaging in any lab-on-a-chip ...

Acoustofluidic hematocrit determination
Analytica Chimica Acta, 2018Hematocrit (HCT) measurements of blood from patients, blood donors and athletes are routinely performed on a daily basis. These measurements are often performed in centralized hospital labs by whole blood analyzers, which leads to long time-to-result.

Miniaturised acoustofluidic tactile haptic actuator
Soft Matter, 2019Coupling the vibration from a piezoelectric substrate through a liquid microchamber facilitates the deflection of a membrane atop the liquid with sufficiently large deformation to facilitate static and dynamic tactile haptic feedback within a human detectable range.

Portable acoustofluidic nebulizer
The Journal of the Acoustical Society of America, 2019The field of acoustofluidics studies the effects of acoustic waves transferred from piezoelectric solids to small volumes of fluid. The phenomenon of acoustofluidic atomization has been studied for several decades now, and one of its major proposed applications is in pulmonary drug delivery.

Detachable acoustofluidic droplet-sorter
Analytica Chimica ActaCell sorting is crucial in isolating specific cell populations. It enables detailed analysis of their functions and characteristics and plays a vital role in disease diagnosis, drug discovery, and regenerative medicine. Fluorescence-activated cell sorting (FACS) is considered the gold standard for high-speed single-cell sorting. However, its high cost,

Abstract When the acoustic waves or radiation are propagating in liquids, the associated fast-moving and rapidly oscillating pressure and velocity fields can impart a slow non-oscillating velocity component to the liquid or to small particles suspended in the liquid.
