There are billions of tiny packets of cellular material called extracellular vesicles (EVs) that are produced by cells and released into each person's blood, saliva, and other bodily fluids. EVs contain invaluable information, such as proteins and genetic material, from their original cell, which can provide insight about the status of the body. Scientists have been trying to leverage EVs for their diagnostic and therapeutic potential but have struggled to do so in a fast and cost-effective way.
