In biology, they constitute the frame of the cytoskeleton in form of F-actin and micro tubular networks and amyloids are responsible for a large number of diseases such as Alzheimer disease.The mechanical properties of complex fluids containing such rod-like colloids are hugely affected by flow via the particle orientation. The morphology of rods, thereby, plays a key role in the microscopic behavior which leads to the macroscopic rheological response.We present a combination of Rheology and Small Angle Neutron Scattering (Rheo-SANS) to resolve the orientational ordering of rodlike viruses under steady shear flow in the 2 relevant planes, the flow-gradient and the flow-vorticity plane. The full orientational order tensor can be resolved in this way, as has been shown earlier [1]. By bio-engineering viruses with different morphologies, we are able to study the influence of geometry and stiffness on the shear thinning behavior of dilute to semi-dilute rodlike colloidal suspensions without polydispersity issues.From Fig.1, it is seen that that length and stiffness have an enormous effect on the orientational ordering. The viscosity of the fd-Y21M virus (Lc=910 nm, Lp=9.9 μm) decreases less with shear rate than that of pf1 (Lc=1.96 μm, Lp=2.2 μm) because the order increase is considerably less.[1] C. Lang, J.
