Hemocompatibility assessment. (A) Hemocompatibility of ELR-gels assessed using the C5 complement convertase activity. Control materials used for comparison: medical steel (MS) and polydimethylsiloxane (PDMS). (B) Evaluation of adhered platelets based on SEM images. Results are plotted as the mean of three different experiments ± standard deviation. (C) SEM images of (i,ii) ELR hydrogel, (iii,iv) GORE-TEX®, and (v,vi) fibrin-gel after 1 h in contact with platelet rich plasma. Activated and fully activated platelets were covering fibrin and GORE-TEX® surfaces, while ELR surfaces presented minimal platelet adhesion. In the images ii, iv and vi, the ELR and GORE-TEX® scaffolds were colored in blue, the platelets with a spread morphology in gold and the more rounded platelets in salmon. Scale bars: (i,iii,v): 10 μm; (ii,iv,vi) 2 μm.
