Figure 3. Viscoelastic Properties of Drug-Induced Aggregates.
A. Shear stress at increasing levels of shear strain for a sample of 10 mg/mL HIV-1 INF185H•1 mM BI-224436 deformed at a constant shear rate of 0.15 s−1 showing the initial elastic response followed by an abrupt fracture of the sample. B. Viscosity vs shear rate at steady shear deformation for very large strains at which intermolecular bonds are continuously broken and reforming, and elongated structures orient in the direction of flow to an extent that depends on the rate of deformation.
