2. 1. On acoustic particle and cell manipulation in microfluidic systems

   Author : Filip Petersson; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medicin människa och djur ; Natural science; Naturvetenskap; Technological sciences; Teknik; acoustic particle manipulation standing wave; acoustic radiation force; laminar flow; Medicine human and vertebrates ; microparticles; ultrasound; lab-on-a-chip; µ-TAS; separation; cells; microfabrication; microtechnology; microfluidics;

   Abstract : The combination of laminar flows in microfabricated channels and acoustic forces induced in ultrasonic standing wave fields offers new possibilities for advanced particle and cell manipulation in lab-on-a-chip applications as well as in relatively high throughput applications. Acoustic particle manipulation systems can be used e.g. READ MORE

4. 2. Acoustic Forces in Cytometry and Biomedical Applications: Multidimensional Acoustophoresis

   Author : Carl Grenvall; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Microfluidics; Ultrasound; Multinode; Cell Sorting; Particle Positioning; Cytometry; Lab-on-a-Chip; µTAS; Binary Separation; Acoustic Barriers; Acoustic Particle Manipulation; Acoustic Standing Waves; Blood Separation; Milk Analysis;

   Abstract : Over the last decades the ongoing work in the fields of Lab-on-a-Chip and Micro-Total-Analysis-Systems has led to the discovery of new or improved ways to handle and analyse small volumes of biofluids and complex biosuspensions. The benefits of working on the microscale include: miniaturization of the analysis systems with less need for large sample volumes; temporal and spatial control of suspended particle/cell positions; low volume sheath flow lamination or mixing; novel separation techniques by using forces inherent to the microscale domain; precise regulation of sample temperatures and rapid analysis with less volumes needed to be processed.

5. 3. On microchannel acoustophoresis - Experimental considerations and life science applications

   Author : Per Augustsson; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microtechnology; microfluidics; lab on a chip; separation; acoustophoresis; ultrasound; acoustic resonance; acoustic radiation force; phage display; circulating tumour cells; acoustofluidics;

   Abstract : This thesis presents experimental studies of microchannel acoustophoresis, a technique for manipulation of microscopic objects in suspension by means of acoustic radiation forces induced by ultrasonic standing wave fields. By arranging an acoustic resonance across the width of a microchannel, the path of individual cells or microparticles can be deflected orthogonally to the fluid flow. READ MORE

6. 4. Ultrasonic Fluid and Cell Manipulation

   Author : Mathias Ohlin; Martin Viklund; Hans Hertz; Peter Glynne-Jones; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D cell culture; Acoustic streaming; Acoustofluidics; Cell manipulation; High-resolution imaging; Multi-well; Microplate; Natural killer cell; Piezo; Radiation force; Solid tumor; Solubilization; Spheroid; Standing wave; Temperature control; Transducer; Trapping; Ultrasonic; Fysik; Physics; Biological Physics; Biologisk fysik;

   Abstract : During the last decade, ultrasonic manipulation has matured into an important tool with a wide range of applications, from fundamental cell biological research to clinical and industrial implementations. The contactless nature of ultrasound makes it possible to manipulate living cells in a gentle way, e.g. READ MORE

7. 5. Acoustic separation and electrostatic sampling of submicron particles suspended in air

   Author : Ramin Imani Jajarmi; Etienne Robert; Lisa Prahl Wittberg; Laszlo Fuchs; Martin Wiklund; Klas Engvall; Jeremy Hawkes; Michel Cervantes; Mats Åbom; Olga Roditcheva; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic; separation; acoustophoresis; Engineering Mechanics; Teknisk mekanik;

   Abstract : We investigate experimentally the effects of acoustic forces on submicron aerosol in a channel flow. This technique can potentially overcome some of the limitations of conventional separation systems and provide advanced manipulation capabilities such as sorting according to size or density.
