Abstract: | The hemocompatibility of functionalized polymeric liposome particles (diameter: 20-32 nm), which have a synthetic porphinato-iron complex in their polymerized bilayers and can carry oxygen, was studied in vitro. The ultramicroparticles did not induce hemolysis, platelet aggregation and plasma coagulation directly and were stable against hydrolysis by phospholipases A2 and D. |
