Abstract
Throughout a lifetime, articular joints experience many loading cycles and are prone to mechanical degradation. To safeguard the cartilage in these joints, the synovial fluid acts as a natural lubricant. However, degenerative joint diseases, like osteoarthritis, alter the composition of synovial fluid, diminishing its protective properties. In such cases, exogenous lubricants or viscosupplements can be injected to enhance the compromised synovial fluid's function. Scientists are now developing next-generation viscosupplements, based on hyaluronic acid (HA), that can better bind to and adhere to cartilage. Additionally, non-HA-based viscosupplements offer benefits over HA-based ones, as they possess more intricate molecular architectures, such as dendrimer or bottlebrush-like structures. These viscosupplements draw inspiration from natural molecules present in synovial fluid, providing them with a distinct advantage.
期刊介绍:
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
