Hydrogel surfaces are of great importance in numerous applications ranging from cell-
growth studies and hydrogel-patch adhesion to catheter coatings and contact lenses. A …

As soft aqueous hydrogels have moved from new materials to the basis for real engineered
devices in the last 20 years, their surface friction and lubrication are emerging as critical …

The development of a hydrogel-based synthetic cartilage has the potential to overcome
many limitations of current chondral defect treatments. Many attempts have been made to …

Biological tissues subjected to rubbing, such as the cornea and eyelid or articular cartilage,
are covered in brushy, hydrated mucous structures in order to reduce the shear stress on the …

Hydrogels are often used as model systems for articular cartilage due to similarities in their
tribological properties. However, neither the structures nor the friction mechanisms of either …

To understand the dissipative mechanisms in soft hydrogel lubrication, polyacrylamide
(PAAm) hydrogels with two distinct surface structures were examined under various contact …

Hydrogels, which can withstand large deformations and have stable chemical properties,
are considered a potential material for cartilage repair. However, hydrogels still face some …

Hydrogels have a distinct combination of mechanical and water-transport behaviors. As
hydrogels stiffen when they de-swell, they become less permeable. Here, we combine de …

Soft contact lenses are medical devices made from aqueous polymeric gels that are worn on
the eye to correct refractive errors. These devices interrupt the natural contact pairing …

This topical review focuses on applying the basics of the classical Coulomb–Amontons (CA)
law of friction to describe bioinspired articulating systems of extremely low values of …
