Mechanical engineers at Duke University have devised a method for spinning individual droplets of liquid to concentrate and separate nanoparticles for biomedical purposes. The technique is much more efficient than traditional centrifuge approaches, working its magic in under a minute instead of taking hours or days, and requires only a tiny fraction of the typical sample size. The invention could underline new approaches to applications ranging from precision bioassays to cancer diagnosis.
The results…
