  5. 3. Acoustic Standing Wave Manipulation of Particles and Cells in Microfluidic Chips

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

    Abstract : The rise of MEMS and µTAS techniques has created a whole new family of microfluidic devices for a wide range of chemical and biomedical analyses to be performed on small Lab-on-a-chip platforms. The operations often include small samples of particle or cell suspensions on which separation, mixing, trapping or sorting is performed. READ MORE
