Nanoscale Horizons

Osaka Metropolitan University researchers have used the power of laser light to accelerate the reaction between cancer cell-derived extracellular vesicles—a kind of nanoparticle—and antibody-modified microparticles. The three-dimensional structure of the resulting aggregates was then analyzed using a confocal optical system. The results demonstrated the ability to measure, within 5 minutes, approximately 1,000 to 10,000 nanoscale EVs contained in a 500 nL sample.
