Abrégé
(EN)
Calcium-phosphate nanofiber matrices comprising randomly dispersed crystalline calcium-phosphate nanofibers are provided. The nanofibers are synthesized using sol-gel methods combined with electrospinning. The nanofibers may be hollow, solid or may comprise a calcium-phosphate shell surrounding a polymer containing inner core to which biologically functional additives may be added. The nanofiber matrices may be used to culture bone and dental cells, and as implants to treat bone, dental or periodontal diseases and defects.
(FR)
L'invention concerne des matrices de nanofibres de phosphate de calcium, comprenant des nanofibres de phosphate de calcium cristallin dispersées de manière aléatoire. Les nanofibres sont synthétisées à l'aide de procédés sol-gel associés à un électrofilage. Les nanofibres peuvent être creuses, solides ou comporter une enveloppe de phosphate de calcium entourant un polymère contenant un cœur intérieur auquel des additifs biologiquement fonctionnels peuvent être ajoutés. Les matrices de nanofibres peuvent être utilisées pour cultiver des cellules osseuses et dentaires, et en tant qu'implants pour traiter des maladies et des troubles osseux, dentaires ou parodontaux.
