Title (EN) SOL-GEL DERIVED BIOACTIVE GLASS POLYMER COMPOSITE
(FR) COMPOSITE POLYMERE-VERRE BIOACTIF DERIVE D'UN SOL-GEL
Abstract: front page image
(EN)A bioactive sol-gel solution includes a biocompatible polymer, a gelable inorganic base material, and at least one calcium and phosphorous molecular species. The base material can be an alkoxide, such as TEOS. The polymer acts as a viscosity modifier to the sol or gel, increases the viscosity range over which fibers can be sprayed or spun, and broadens the time period over which fibers can be sprayed or spun. A bioactive glass composite can be formed from the bioactive sol-gel solution, including a fibrous form. Fibers can serve as a scaffold for cell growth and in the repair of hard or soft tissue defects.
(FR)L'invention concerne une solution sol-gel bio-active comprenant un polymère biocompatible, un matériau de base inorganique gélifiable, et au moins une espèce moléculaire de calcium et de phosphore. Le matériau de base peut être un alkoxyde, tel que le TEOS. Le polymère agit en tant que modificateur de viscosité du sol ou du gel, augmente la plage de viscosité au delà de laquelle les fibres peuvent être atomisées ou filées, et élargit la durée pendant laquelle ces fibres peuvent être atomisées ou filées. Il est possible de former un composite de verre bioactif à partir de la solution bio-active sol-gel, incluant une forme fibreuse. Les fibres peuvent servir de structure pour la croissance cellulaire et dans la réparation de défauts de tissus mous et durs.
