Extracellular vesicle-derived microRNA (EV-miRNA) represent a promising cancer biomarker for disease diagnosis and monitoring. However, existing techniques to detect EV-miRNA rely on complex, bias-prone strategies and preprocessing steps, making absolute quantification highly challenging. This work demonstrates the development and application of a method for quantitative and multiplex detection of EV-miRNA, via rolling circle amplification within encoded hydrogel particles. By a one-pot extracellular vesicle (EV) lysis and microRNA capture step, we avoid the bias and losses associated with standard RNA extraction techniques. The system offers a large dynamic range (3 orders of magnitude), ease of multiplexing, and a limit of detection down to 2.3 zmol (46 aM), demonstrating its utility in clinical applications based on liquid biopsy tests. Furthermore, orthogonal measurements of EV concentrations coupled with the direct, absolute quantification of miRNA in biological samples results in quantitative measurements of miRNA copy numbers per volume sample, and per extracellular vesicle. A facile technique for quantitative and multiplex detection of extracellular vesicle-derived microRNA is presented based on rolling circle amplification within encoded hydrogel particles. The fluorescence-based system offers a large dynamic range and low limit of detection (2.3 zmol, 46 aM), enabling direct and absolute quantification of microRNA biomarkers in biological samples, amenable for use in liquid biopsy tests.
