Double network (DN) gels are anomalously robust but soft and wet materials, whose maximum stress in compression reaches 30MPa and surface friction coefficient reaches 0.001 simultaneously. The DN gels also have shock absorbency, permeability, and biocompatibility. Thus it is expected that the DN gels will be applied to artificial joints, artificial cartilages, and artificial blood vessels. In t...

Extended wear of soft contact lenses is associated with an increased risk of Pseudomonas aeruginosa infection of the cornea. To assess the role of bacterial adherence in the pathogenesis of these infections, superficial corneal epithelial cells and leukocytes from ten patients who use extended-wear soft lenses and ten control eyes were compared for their propensity to attach P. aeruginosa in vi...
