  • NANOFIBERS, NANOTUBES AND NANOFIBER MATS COMRPISING CRYSTALLINE METAL OXIDES AND METHODS OF MAKING THE SAME
    Publication number: 20160138192
    Abstract: Inorganic nanofibers comprise an inorganic matrix material surface functionalized with at least one metal oxide in crystalline form. Crystal growth on external surfaces may occur in substantial alignment with a longitudinal axis of the nanofibers, and the crystals are typically between about 10.0 nm and 30.0 nm in size. The nanofibers may be hollow (i.e., nanotubes) or they may be randomly dispersed together in the form of a nanofiber mat. Methods for making the nanofibers comprise spinning a dispersion comprising linear polymers and metal oxide precursors.

  • Electrospun Calcium Phosphate Nanofibers
    Publication number: 20130313735
    Abstract: 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.
