    Sammanfattning : 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.

  3. 3. Cell Sorting in Pillar Arrays based on Electrokinetics and Morphology

    Författare :Bao Dang Ho; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell Sorting; Label-Free Separation; Deterministic Lateral Displacement; Electrokinetics; Fysicumarkivet A:2018:Dang Ho;

    Sammanfattning : Deterministic Lateral Displacement (DLD) is a method capable of sorting cells based on size where mechanicalinteractions between a sufficiently large particle and obstacles in a microfludic pillar array force the particle tofollow a different trajectory than their smaller counterparts, resulting in continuous lateral separation. To extendthe capability of DLD, electrical interaction between particles and pillars can be employed to complement themechanical interaction, making electrical/dielectric properties additional parameters for sorting.

  4. 4. Hydrodynamic flow for deterministic sorting of cell-membrane components

    Författare :Björn Johansson Fast; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; Diffusion; Microfluidics; Native membrane vesicles; Single particle tracking; Protein enrichment; Hydrodynamic forces; Supported lipid bilayer; Size determination;

    Sammanfattning : The biological membrane, an amphiphilic structure that is the barrier between the cell interior and exterior, is one of the vital building blocks of all cells. Not only does it define the outer boundaries of the cell, it also carries important biological function by virtue of the proteins and other molecules that constitute the membrane, the function of which is in turn intimately coupled to their association with the lipid-based membrane.

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

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

    Sammanfattning : 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. LÄS MER
