Tribological evaluation of hydrogels for artificial articular cartilage
Lopes, J. L.; Machado, J. M.; Castanheira, L.; Granja, P. L.; Gama, F. M.; Dourado, Fernando; Gomes, J. R.Bacterial cellulose (BC) is a natural and biocompatible gel with unique properties, such as high water holding capacity, ultra-fine fibre network and high strength that make it an interesting material for biotribological purposes. In this work, unmodified BC pellicles were grown from Gluconacetobacter xylinus in order to be used as tribological samples against bovine articular cartilage (BAC) in the presence of...
Friction and wear behaviour of bacterial cellulose against articular cartilage
Lopes, J. L.; Machado, J. M.; Castanheira, L.; Granja, P. L.; Gama, F. M.; Dourado, Fernando; Gomes, J. R.Bacterial cellulose (BC) is a natural and biocompatible material with unique properties, such as high water holding capacity, ultra-fine fibre network and high strength that makes it an attractive material for the repair of articular cartilage lesions. However, data on the tribological properties of BC is very scarce, particularly if natural articular cartilage is involved in the contact. In this work, unmodifi...
