Themed collection Acoustofluidics

This tutorial outlines some basic fluidic configurations for acoustophoresis based sample decomplexing and detail the transport phenomena that impact the outcome of an acoustophoresis based affinity extraction experiment or a cell medium exchange step.

This article discusses the design, construction and applications of planar resonant devices for acoustic manipulation of particles and cells.

We present and analyze a number of scaling laws relevant for microsystem acoustophoresis. Such laws are useful both in understanding, designing, and analyzing acoustofluidic devices.

This acoustofluidics tutorial focuses on different applications of continuous flow microfluidic acoustic standing wave manipulation such as cell and particle concentration, separation and fractionation.

We present the theory of acoustic radiation force; a second-order, time-averaged effect responsible for the acoustophoretic motion of suspended, micrometre-sized particles in an ultrasound field.

This acoustofluidics tutorial describes different measurement techniques used for the experimental characterization of ultrasonic particle manipulation devices.

This tutorial covers some of the basics in designing and building microfluidic acoustic resonators and will hopefully be a comprehensive and advisory document to assist the interested reader in creating a successful acoustophoretic device.

This acoustofluidics tutorial covers the linear equations of piezoelectricity and their application to the excitation of acoustic fields for ultrasonic particle manipulation including a FEM model.

This acoustofluidics tutorial covers the continuum mechanics of structures and their interaction with a fluid used for ultrasonic particle manipulation devices.

We present perturbation theory of acoustic fields in fluids and apply the result in a study of acoustic resonance modes in microfluidic channels.

Governing equations for microfluidics and basic flow solutions are presented. Equivalent circuit modeling for determining flow rates in microfluidic networks is introduced.
