Surface modification tailors the characteristics of biomimetic coatings nucleat...
Oliveira, A. L.; Elvira, C.; Vásquez, Blanca; San Román, J.; Reis, R. L.This work describes the influence of surface pretreatments over the nucleation and growth of an apatite layer, formed by a biomimetic process, on which a bioactive glass is used as a precursor of the calcium-phosphate (Ca-P) formation on the materials surface. SEVA-C, a corn starch-based biodegradable blend, was used as substrate. The surfaces were pretreated during various periods by: (i) physical methods, nam...
New starch-based thermoplastic hydrogels for use as bone cements or drug-delive...
Pereira, C. S.; Vásquez, Blanca; Cunha, A. M.; Reis, R. L.; San Román, J.The development of new biodegradable hydrogels, based on corn starch/cellulose acetate blends, produced by free-radical polymerization with methyl methacrylate monomer (MMA) and/or an acrylic acid monomer (AA), is reported. The polymerization was initiated by a redox system consisting of a benzoyl peroxide and 4-dimethlyaminobenzyl alcohol at low temperature. These hydrogels may constitute an alternative to the...
