Nanoparticles wiggling through mucus may predict severe COPD

ScienceDaily.com: Nanotechnology News - Mon, 09/30/2019 - 18:09
In a proof-of-concept experiment, researchers say they have successfully used microscopic human-made particles to predict the severity of patients' chronic obstructive pulmonary disease (COPD) by measuring how quickly the particles move through mucus samples. The technique, say the researchers, could eventually help doctors deliver more effective treatments sooner.
