Theoretical aspects of microscale acoustofluidics
نویسنده
چکیده
In this contribution, I summarize some of the recent results within theory and simulation of microscale acoustofluidic systems that I have obtained in collaboration with my students and international colleagues. The main emphasis is on three dynamical effects induced by external ultrasound fields acting on aqueous solutions and particle suspensions: The acoustic radiation force acting on suspended microand nanoparticles, the acoustic streaming appearing in the fluid, and the newly discovered acoustic body force acting on inhomogeneous solutions.

Microscale acoustofluidics: Microfluidics driven via acoustics and ultrasonics
This article reviews acoustic microfluidics: the use of acoustic fields, principally ultrasonics, for application in microfluidics. Although acoustics is a classical field, its promising, and indeed perplexing, capabilities in powerfully manipulating both fluids and particles within those fluids on the microscale to nanoscale has revived interest in it. The bewildering state of the literature a...

Acoustofluidics 18: Microscopy for acoustofluidic micro-devices.
In 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 device. The discussion includes basic principle...

In Part 10 of the thematic tutorial series "Acoustofluidics-exploiting ultrasonic standing waves forces and acoustic streaming in microfluidic systems for cell and particle manipulation", 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.
