This review covers microfluidic devices for rare cell isolation, comparing electrokinetic and non-electrokinetic methods. Advances are highlighted, but improving viability and purity for direct biological sample processing remains key.

Area of Science:

  • Biotechnology
  • Microfluidics
  • Cellular Biology

Background:

  • Rare cell isolation is crucial for diagnostics and research.
  • Existing microfluidic devices face challenges in efficiency and purity compared to bulk methods.
  • Low starting concentrations of target cells complicate isolation.

Purpose of the Study:

  • To review and compare existing rare cell capture methods in microfluidic devices.
  • To highlight advances in both electrokinetic and non-electrokinetic approaches.
  • To identify areas for improvement in rare cell isolation technologies.

Main Methods:

  • Review of non-electrokinetic methods: immobilization, size-based sorting, sheath flow.
  • Review of electrokinetic methods: dielectrophoresis (DEP) with electrode-based and insulative geometries.
