    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

  4. 2. Cell and Particle Trapping in Microfluidic Systems Using Ultrasonic Standing Waves

    Author : Mikael Evander; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic particle manipulation; standing waves; trapping; ultrasound; cell handling; particle handling; Microsystem technology; lab on a chip; microfluidics;

    Abstract : Analysis methods are currently being miniaturized in order to save time and money while achieving higher sensitivities. The ultimate goal is to create a lab-on-a-chip where all analysis steps and instruments can be automated and integrated into a single chip. READ MORE

  5. 3. Ultrasound-assisted Interactions of Natural Killer Cells with Cancer Cells and Solid Tumors

    Author : Athanasia Christakou; Martin Wiklund; Sabeth Verpoorte; KTH; []
    Keywords : Natural killer cell; cytotoxicity; heterogeneity; multiwell microchip; biocompatibility; ultrasonic cell manipulation; 3D cell culture; solid tumor; spheroid; high-resolution imaging; Biologisk fysik; Biological Physics;

    Abstract : In this Thesis, we have developed a microtechnology-based method for culturing and visualizing high numbers of individual cells and cell-cell interactions over extended periods of time. The foundation of the device is a silicon-glass multiwell microplate (also referred as microchip) directly compatible with fluorescence microscopy. READ MORE

  6. 4. On-chip Ultrasonic Sample Preparation

    Author : Ida Sadat Iranmanesh; Martin Viklund; Johan Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ultrasound; Sample preparation; Particle manipulation; Fysik; Physics; Biological Physics; Biologisk fysik;

    Abstract : Acoustofluidics has become a well-established technology in the lab-on-a-chip scientific community. The technology involves primarily the manipulation of fluids and/or particles in microfluidic systems. READ MORE

  7. 5. Acoustic manipulation for cell and spheroid cellomics

    Author : Karl Olofsson; Martin Viklund; Maria Tenje; KTH; []
    Keywords : Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Abstract : Ultrasonic standing wave (USW) particle manipulation has during the last two decades matured into a valuable tool to combine with microfluidics. Acoustophoresis, migration through sound, is the result of the acoustic radiation force acting on particles suspended in an acoustic field.
