Cardiovascular disease is the leading killer of people worldwide. Current treatments include organ transplants, surgery, metabolic products and mechanical/synthetic implants. Of these, mechanical and synthetic implants are the most promising. However, rejection of cardiovascular implants continues to be a problem, eliciting a need for understanding the mechanisms behind tissue-material interaction. Recently, bioartificial implants, consisting of synthetic tissue engineering scaffolds and cells, have shown great promise for cardiovascular repair. An ideal cardiovascular implant surface must be capable of adhering cells and providing appropriate physiological responses while the native tissue integrates with the scaffold. However, the success of these implants is not only dependent on tissue integration but also hemocompatibility (interaction of material with blood components), a property that depends on the surface of the material. A thorough understanding of the interaction of cardiovascular cells and whole blood and its components with the material surface is essential in order to have a successful application which promotes healing as well as native tissue integration and regeneration. The purpose of this research is to study polymeric nanowire surfaces as potential interfaces for cardiovascular applications by investigating cellular response as well as hemocompatibility.
