Storage (red filled squares) and loss (red empty squares) moduli of whole human blood with Hct = 44% determined by passive microrheology at T = 27 °C, within the viscoelastic linear range.
Storage (red filled squares) and loss (red empty squares) moduli of blood from Figure 1 rescaled to 37 °C using time-temperature superposition, and the fits to multi-mode Giesekus (solid line) and sPTT (blue dots) models. Figure inset shows comparison between the steady shear viscosity curve of whole real blood (red circles) obtained experimentally by Valant et al. 30 and the model fits.
Viscosity curves for the four analogue solutions in comparison with the viscosity curves of whole human blood of Valant et al. 30 (average between F1 and M3 samples and error bars representing the standard deviation of their averaged values) and Thurston's data. 4 For the analogue solutions open and closed symbols denote measurements with parallel plates and cone-plate, respectively.
Storage (G′, closed symbols) and loss (G″, open symbols) moduli measured by passive microrheology. Comparison between data for the blood analogue solutions at 20 °C and data for real blood (Hct = 44%) shifted to 37 °C. For real blood the results shown are the average of three measurements. The error bars correspond to differences at P < 0.05 (Student's t-test).
