Graphical Abstract

A fluid multivalent magnetic interface was engineered in a microfluidic chip to improve the kinetics and thermodynamics of biomolecular recognition for efficient isolation of tumor-derived extracellular vesicles (T-EVs). With the assistance of magnetic and flow fields, this interface balanced affinity, selectivity, reversibility, and extendibility, enabling high-throughput recovery of T-EVs for protein profiling.

Abstract

Isolation and analysis of tumor-derived extracellular vesicles (T-EVs) are important for clinical cancer management. Here, we develop a fluid multivalent magnetic interface (FluidmagFace) in a microfluidic chip for high-performance isolation, release, and protein profiling of T-EVs. The FluidmagFace increases affinity by 105-fold with fluidity-enhanced multivalent binding to improve isolation efficiency by 13.9 % compared with a non-fluid interface. Its anti-adsorption property and microfluidic hydrodynamic shear minimize contamination, increasing detection sensitivity by two orders of magnitude. Moreover, its reversibility and expandability allow high-throughput recovery of T-EVs for mass spectrometric protein analysis. With the chip, T-EVs were detected in all tested cancer samples with identification of differentially expressed proteins compared with healthy controls. The FluidmagFace opens a new avenue to isolation and release of targets for cancer diagnosis and biomarker discovery.
