“…After the addition of 20 cm 3 NaOH (Avantor Performance Materials Poland), the pH changed, i.e., to 6.80 after the addition of 50 cm 3 . In the experiments, the Britton and Robinson buffer [17] was used, which is a buffer used in standard biochemical analysis due to its wide pH range (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) and its composition that does not affect the biological membrane. The pH of the electrolyte solution was controlled during all measurements [18].…”

“…Many scientists have been able to apply knowledge about natural surfaces in relative motion, and their friction or lubrication and wear, to the creation of new lubricants, such as surface-grafted polymer brushes [4][5][6][7][8][9][10][11][12]. Bayer [13] has presented information about new materials and modified lubricin structures for low friction.…”

Some solid lubricants are characterized by a layered structure with weak (van der Waals) inter-interlayer forces which allow for easy, low-strength shearing. Solid lubricants in natural lubrication are characterized by phospholipid bilayers in the articular joints and phospholipid lamellar phases in synovial fluid. The influence of the acid–base properties of the phospholipid bilayer on the wettability and properties of the surface have been explained by studying the interfacial tension of spherical lipid bilayers based on a model membrane. In this paper, we show that the phospholipid multi-bilayer can act as an effective solid lubricant in every aspect, ranging from a ‘corrosion inhibitor’ in the stomach to a load-bearing lubricant in bovine joints. We present evidence of the outstanding performance of phospholipids and argue that this is due to their chemical inertness and hydrophilic–hydrophobic structure, which makes them amphoteric and provides them with the ability to form lamellar structures that can facilitate functional sliding. Moreover, the friction coefficient can significantly change for a given phospholipid bilayer so it leads to a lamellar-repulsive mechanism under highly charged conditions. After this, it is quickly transformed to result in stable low-friction conditions.

“…A very important review on this subject by Mocny and Klok [48] brings together tribological properties of surface-attached synthetic polymers with other considerations such as tribological tools of characterization and the lubrication properties of three common surface-attached polymer brushes, namely, hydrophilic, hydrophobic, and fluorinated brushes. The readers should also refer to another review by Yang and Zhou [49] on the applications of polymer brushes for antibiofouling and lubrication. Another review paper by Krishnamoorthy et al [50] discusses advances in surface-initiated polymer brushes for biomedical applications including membrane science, bio-sensing, cell culture, antibacterial coatings, and regenerative medicine.…”

Articular cartilage surrounds the ends of diarthrodial joints (most common movable joints) and during motion, it experiences a wide range of loading conditions while remaining under exceedingly low-friction and wear-free conditions. This remarkable tribological performance stems from complex interactions between the synovial fluid and articular cartilage. In fact, lubricin and hyaluronic acid (HA) that are part of the synovial fluid are now known to be the key contributors to effective joint lubrication and wear protection. Studies involving animal models and artificial systems suggest that lubricin and HA molecules may work in tandem to produce a highly synergistic effect for lubrication. However, latest observations suggest that lubricin has significant potential for protecting the articular joints, probably more than HA. Recently, lurbicin-related friction regulation in soft eye tissues, where much lower forces are involved compared to knee joints for instance, has been shown to be related to dry eye disease and contact lens discomfort. As such, lubricin's role in natural friction regulation is very complex. Moreover, partially unresolved water-lubricin interactions are essential for lubrication and load carrying function in the joints. The chemical structure of lubricin has inspired several chemists to synthesize new copolymers and polymer brushes that function just like lubricin in order to design new synthetic or bio-based lubricants with ultra-low-friction coefficients. Hence, lubricin has emerged as a key natural molecule for bioinspired tribology. The aim of this review is to present the latest advances in understanding of lubricin's function in joint lubrication and in soft tissue friction (i.e., human eye) and document what has been achieved so far in transforming this biomedical knowledge into new polymer design for advanced engineering tribology. It is hoped that this review will catalyze research and development efforts in obtaining very stable and high load-bearing polymer-based ultra-low-friction surfaces via biomimicry.
