Researchers at the Schulich School of Engineering at the University of Calgary are developing a novel technology called EXOSense to detect cancer at earlier stages using tiny particles found in bodily fluids. With cancer claiming over 10 million lives globally each year, early detection is critical for improving survival rates and reducing healthcare costs. However, current diagnostic tools often fail to identify the disease until it has progressed significantly, largely because traditional biomarkers are rare and short-lived in the early stages. The new approach focuses on small extracellular vesicles, which are microscopic, bubble-like particles released by cells into fluids like blood and urine. These particles act as a natural communication system, carrying genetic material and other biomolecules that reflect the health of the originating cells. Crucially, these vesicles can carry disease-specific information long before symptoms appear or traditional biomarkers become detectable. Isolating these particles is scientifically challenging due to their minuscule size, which is approximately 500 times smaller than a pollen grain, and their presence amidst complex biological mixtures. Previous methods often required adding foreign labels or antibodies to the particles, which can alter their properties and compromise accuracy. To address this, the University of Calgary team developed a label-free technique that utilizes the natural electrical properties of the vesicles. This method uses gentle electrical forces to capture the particles directly from bodily fluids without damaging them or stripping away vital information. The technology is currently patent pending. The research team aims to transition EXOSense from the laboratory to clinical use by integrating it into miniaturized, cost-effective platforms based on microfluidic technology. The goal is to create a simple, non-invasive liquid biopsy test that requires only a single drop of biofluid. By making the technology accessible and affordable, the researchers hope to expand diagnostic capabilities to underserved communities with limited laboratory infrastructure. Although still in the development phase and awaiting testing with actual patient samples, the EXOSense platform promises to provide physicians with a reliable snapshot of cellular health. This could enable earlier and more informed treatment decisions, ultimately reducing the global burden of cancer. The innovation represents a significant step toward interpreting the "secret language" of cells to save lives through earlier intervention.
