Blood biocompatibility assays. (A) Red blood cell (RBC) hemolysis assay. (B) Zoomed in RBC hemolysis assay showing Cy5-TMV, PEG-Cy5-TMV, and Cy5-SNP do not lyse RBCs. (C) Effect of Cy5-TMV, PEG-Cy5-TMV, and Cy5-SNP on clotting (normalized to saline control), measured in rotational thromboelastometry (ROTEM). There were no significant changes in the combined clotting time (CT+CFT) and maximum clot firmness (MCF) compared to the saline control (dotted line). Error bars represent S.D.
