Advanced Multipurpose Spectroscopic Nanobio-Device for Concurrent Lab-on-a-Chip Label-Free Separation and Detection of Extracellular Vesicles as Key-Biomarkers for Point-of-Care Cardiovascular Disease Diagnostics.

ABSTRACT: The global aging population presents a major public health challenge, with cardiovascular diseases (CVDs) remaining the leading cause of death worldwide. Often asymptomatic in early-stages, CVDs are frequently undiagnosed until critical events like myocardial infarction or stroke occur. To address this gap, an advanced integrated multipurpose spectroscopic lab-on-a-chip bionano-device has been developed for early CVD detection through extracellular vesicle (EV). EVs, which reflect the molecular state of their originating cells, are separated and analyzed using the combined Raman spectroscopy's molecular specificity with AI-driven classification from clinical CVD biofluids. AIMSpec-LoC unprecedently achieves rapid, label-free, size-based separation of EV subtypes, including small, mid and l
