Key Points

The research aims to develop a device for sensitive detection of extracellular vesicle-derived miRNAs without amplification.
Utilized a digital microfluidic integrated SiNW array FET for analysis.
Enabled low-volume EV enrichment.
Discriminated single-base mismatches in miRNA detection.
Successfully distinguished EV-miRNA expression between normal and M1 disease states.
Achieved ultrasensitive detection of rare miRNAs without amplification.

Abstract

M, the device discriminates single-base mismatches and reliably distinguishes EV-miRNA expression differences between normal and M1 disease states. This integrated approach enables low-volume EV enrichment and ultrasensitive EV-miRNA detection, offering a promising platform for clinical analysis of rare samples.
