Biocompatibility to widen scope of biomaterial applications
...terials' applications. "Thrombosis involving blood coagulation
and adhesion of blood platelets to biomaterial surfaces as well as fibrous-tissue encapsulation of biomaterials that are implanted in soft tissues are two challenging issues for researchers in quest of biocompatibility," says Technical Insights Analy...
Nonalcoholic beverages may impart cardiovascular benefits without the negative effects of alcohol
