Technical University of Denmark, Copenhagen

In the Theoretical Microfluidics Group, Department of Micro- and Nanotechnology, Technical University of Denmark, we work on theoretical aspects of ultrasound acoustofluidics in microsystems. Currently our focus is on the study of acoustic resonances, acoustic radiation force on microbeads/cells, and acoustic streaming. Our goal is to deepen the basic physical understanding of acoustofluidics, and in close collaboration with experimental groups to apply our theoretical insight and numerical simulations in the development of new biotechnology applications.

We investigate both macro and microscopic devices for acoustic manipulation for predictable positioning of microsized particles (e.g. copolymer beads, biological cells, disks and droplets), in one, two and three dimensional patterns, as well as the motion of particles using acoustic radiation forces, streaming and further microfluidic force fields. A strong emphasis is given to the modeling (both analytical and with finite element methods) of the acoustic field, with the goal of predicting the operational frequencies and the patterns achievable. Finally, the combined use of acoustic manipulation with mechanical gripping (e.g. with micromachined microgrippers, see video ) and optical tweezers completes the spectrum of our research.

The nanobiotechnology and lab-on-a-chip group at the dept. of Biomedical Engineering has one of its core topics in the area of ultrasonic particle and cell manipulation in microfluidic systems. Fundamental lab-on-a-chip unit operations are under development enabling continuously flow particle/cell separation, buffer exchange, acoustic valving, cell/particle trapping and rare event sorting. Application in the biomedical field targets bioanalytical and forensic cell sample preparation as well as therapeutical issues in medical blood processing.

At the University of Southampton we have been studying ultrasonic standing waves since 1996, looking at macroscale systems as well as microscale particle manipulation devices. Much of the research is applied to bio-hazard and bio-medical sensing applications, using USW to process sample streams, but also to interact with sensor elements more directly. Currently our research involves working towards the manipulation of DNA strands using USW, a multidisciplinary project involving several schools across the university. Our experience encompasses acoustic simulation, design, microfabrication and the rapid turn-around of micro-milled microfluidic devices.

Ultrasound standing wave activities in the Manchester Miniaturisation Group include: disposable resonant chambers, moving cells onto the surface of cell sensing elements, large scale devices for concentrating cells (for example to filter algae for biofuel), an experimental study of acoustic streaming, manipulating particles in air, and vibration mode modelling in conjunction with laser-vibrometer measurements. Some members of our team are also developing non-acoustic micro-fluidic systems.

In the Ultrasonic manipulation group, Dept. of Applied Physics, Royal Institute of Technology (KTH), we combine microfluidics, acoustics and optics into lab-on-a-chip systems for handling and characterization of cells or other bio-active microparticles. In particular, we develop and investigate ultrasonic cages, called 'sono-cages', integrated in microfluidic chips or multiwell plates. The sono-cages can be used for three-dimensional accurate trapping, positioning and aggregation of mammalian cells. Our primary application field is to investigate immune cell interactions in fully biocompatible systems. More information and publication list is found here:

The Laboratory for Micro Systems (LMS) in the Department for Mechanical and Aerospace Engineering focusses on the physics and applications of microfluidic devices and MEMS. A large part of our work utilises ultrasound and lower frequency vibration for fluid suspension manipulation. Our recent work highlights the possibilities for sorting particles by concurrent use of multiple ultrasonically induced mechanisms in, for example, an open fluid volume or near a bubble. We are also working on the interaction of ultrasound with fluid boundaries and have demonstrated on-demand droplet generation by use of ultrasound to deform an oil/water interface.

Our research interests lies in ultrasonic sensors, ultrasonic transducers fabrication, micro-fabrication, transducer arrays, acoustofluidics, acoustic particle manipulation and piezoelectric materials. Acoustic manipulation enable high throughput, dynamic and precise control of micro-particles such as living cells and drugs carriers. We are also looking at integrated acoustic manipulators with sensor modules to allow further analyses of manipulated particles. Applications of these technologies include all kind of living biological cell studies such as sorting, filtering and concentrating, and further to bio-engineering such as controlled tissue culture.

In the FILMS team of the IEMN Institute, we work on theoretical, numerical and experimental aspects of microscale acoustofluidics. Currently, our work focuses on the development of selective miniaturized acoustical tweezers and stirrers based on a specific kind of waves called acoustical vortices. Our goal is to design some cheap, simple, miniaturized acoustical tweezers that would enable the on-chip 3D selective manipulation of particles, cells and microorganisms, with forces several orders of magnitude larger than their optical counterparts at the same input power. We also dedicate time and effort to understanding the underlying physics and in particular the acoustic radiation force and streaming flow produced by these specific wavefields.
