Overview

Review highlights microfluidic strategies for extracellular vesicle purification and molecular detection, suggesting improved efficiency and sensitivity for noninvasive diagnostics.

Key Points

  • Review recent technological advances in microfluidics for the isolation, purification, and molecular profiling of extracellular vesicles in diagnostic applications.
  • Evaluated conventional extracellular vesicle isolation and detection methodologies, including ultracentrifugation, size-exclusion chromatography, PCR, and ELISA.
  • Assessed microfluidic innovations categorized by hydrodynamic manipulation, external-field application, sample compartmentalization, and micro/nanostructure integration.
  • Conventional isolation and detection workflows exhibit limitations including high sample volume requirements, poor vesicle purity, and inadequate subtyping resolution.
  • Passive hydrodynamic methods—including inertial and viscoelastic flows—and active external energy fields significantly improve vesicle sorting purity and recovery efficiency.
  • Micro- and nanoscale compartmentalization combined with structured nanomaterials substantially elevates analytical sensitivity and specificity for disease-specific vesicle cargo.
