Rheological Comparison of Cystic Fibrosis and Healthy Sputum. Samples of expectorated sputum from a patient with cystic fibrosis and a healthy subject were measured using DLSμR. The range of frequencies over which the healthy sputum was able to be measured is limited by the fast decorrelation of particle movement within the liquid-like sample. The complex modulus of the healthy sputum is lower than that of the cystic fibrosis sputum. Opaque regions indicate one standard deviation from the mean, n = 3.
