Researchers developed a nanotweezers-based method combined with artificial intelligence to analyze extracellular vesicles from milk without requiring fluorescent labels. The technique enables single-particle analysis of these nanoscale biological structures, providing detailed characterization of individual vesicles that would be difficult to achieve with conventional bulk analysis methods. This label-free approach preserves the natural properties of the vesicles while allowing high-throughput examination.
Why it matters
This technology could improve quality control and safety testing of dairy products by enabling rapid, non-destructive analysis of milk components at the nanoscale. The method may also advance research into milk-derived extracellular vesicles, which are being investigated for potential therapeutic and nutritional applications, by providing more accurate single-particle data without chemical modifications that could alter their properties.
