For compiled data on animal erythrocytes and the resulting blood suspensions see: DOI: 10.1201 / b21806 (go to chapter 12), or check publications for the full list of animal blood testing. We are proud that our collaborators used our datasets to model different flow conditions 1-5.

Our current interest turned now on the role of plasma for blood flow. We showed that plasma is elastic under optimized conditions 6, is shear-thinning in swine 7, and creates an stabile halo around RBCs of several species at rest 8, which enlarges their functional diameter. These plasma properties affect coupling and yielding.

Another focus of our work is on bloodstain pattern analysis. Crime scene re-enactment requires substantial blood volumes from human or large animal species, but the type and quality of the blood source can vary significantly between forensic laboratories. Therefore the tests carried out may also vary. We examined the maximum storage time for pig and cow blood withdrawn and stored at optimized conditions and found out that they must be discarded on the 21st day after collection 9,10. Drawn and stored at suboptimal conditions, blood must be disposed of earlier.
