Abstract

Cell-derived microparticles (MPs) in blood are widely proposed as surrogate biomarkers in disease and health monitoring. Herein, we describe a novel inertial microfluidic technology termed as High-resolution Dean Flow Fractionation (HiDFF), to isolate MPs from whole blood directly for vascular health profiling. Clinical utility was demonstrated by rapid MPs isolation and flow cytometry characterization of healthy subjects and type 2 diabetes mellitus (T2DM) patients. Higher endothelialand neutrophil-derived MP were observed in T2DM patients, indicating elevated vascular inflammation and pro-inflammation states. Our results suggest MPs as novel cell-based biomarkers for vascular health point-of-care monitoring and risk stratification in T2DM patients.
