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

    Författare :Bao Dang Ho; NanoLund: Center for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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. Deterministic Lateral Displacement for Cell Separation

    Författare :Si Hoai Trung Tran; NanoLund: Center for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deterministic lateral displacement; Cell Separation; Open microfluidics;

    Sammanfattning : In the fields of medicine and biology, the separation of particles is a central step in many preparative and analytical processes. Deterministic Lateral Displacement (DLD) has been a promising technique in the field of microfluidic particle and cell sorting, specifically for label-free separation with several applications of sorting by size, morphology, and deformation reported in the literature over the last decade.
