Biotribology deals with tribological processes in living organisms and at the interfaces between biological and artificial surfaces. It represents multidisciplinary research area including the aspects of biology, physics of surfaces, material science, chemistry, biomechanics, as well as mechanical engineering. Our research programme aims at the processes of friction, lubrication, and wear within the replacements of large human joints. Further, we are interested in analysis of friction and lubrication of joint cartilage, focusing on the effect of viscosupplementation representing conventional treatment for patients suffering from joint osteoarthritis. Currently, our activities are being extended into other fields, such as eye tribology, tribology of small joint replacements made by 3D printing, or extension of service life of implants due to targeted modification of implant contact surfaces ensuring minimization of friction and wear.
