'Virtual pillars' separate and sort blood-based nanoparticles: Sorting biological nanoparticles 500 times thinner than a human hair could improve a wide variety of diagnostics and treatments

Engineers have developed a device that uses sound waves to separate and sort the tiniest particles found in blood, in a matter of minutes. The technology is based on a concept called 'virtual pillars' and could be a boon to both scientific research and medical applications.
