Biological interface lubrication enhancement

Biological interface lubrication enhancement is not a single molecular entity but an area of research and clinical development focused on improving the lubricating properties of tissue and biomaterial surfaces to reduce friction and wear. This can be achieved by applying exogenous lubricants such as hyaluronic acid or synthetic hydrogels, or by engineering surfaces to promote the binding of bodily lubricants like HA and lubricin at cartilage, ocular, or other tissue surfaces. These interventions aim to restore or mimic the ultra-low friction properties of healthy tissue interfaces, protecting against tissue degeneration and dysfunction observed in diseases such as osteoarthritis or dry eye syndrome[5][1][3][4][6].
