Micro-tornado improves particle-counting technology

Duke University engineers have developed a novel “nozzle” that permits a decades-old technology for detecting tiny particles such as cells or viruses to process even smaller samples without clogging. In use in different forms since the 1950s, Coulter counters measure tiny particles suspended in a fluid as they pass through a sensing opening, or aperture, […] … learn more→
