The Laboratory of Biomechanics and Biomedical Engineering  of the University of Patras has more than 25 years of experience in the fields of biomechanics and biomaterials emphasizing in the domain of cell-material interactions.

Blood compatibility testing using static and dynamic blood-material contact, cell-materila interactions in the case of diffenrent cell cultures, mechanical properties of cells, tissues and biomaterials are some of the main research interests of our group.

More recently nanotechnology and nanoidentation techniques, functionalization of polymeric surfaces via selected biomolecules immobilization techniques as well as techniques to study endothelial cell culture on biomaterials under dynamic (flow, mechanical stress) conditions have been developed.
