Extracellular vesicles, or EVs, are small membrane-bound particles released by nearly all cells. They carry various biological materials, including proteins, RNA, and lipids, which can provide insights into the health of their originating cells.
The ability of EVs to circulate in the bloodstream makes them a promising candidate for non-invasive diagnostic methods, such as liquid biopsies.
As research progresses, single-vesicle profiling may improve the accuracy and utility of liquid biopsies, potentially bringing them closer to routine clinical application.
