guided nerve regeneration (GNR) - Opis:
- The nanocomposite material based on chitosan was obtained and characterized. Commercially produced biopolymer at 85% deacetylization degree was used. The biopolymer matrix was modified with carbon nanofillers such as graphite oxide (GO), carbon nanotubes (CNTs) and nanontubes with the surface affected by carboxyl groups (CNT-COOH). The obtained nanocomposites were formed by means of two methods: casting (to manufacture nanocomposite foils) and liofilization (to manufacture porous nanocomposite materials). Their electrical properties and microstructure were examined. The tests proved that adding the carbon nano-filler results in high resistivity (graphite foils, carbon nanotubes) and also the average size of pores in liofilized materials. Additionally, the electric potential of the materials may be improved by surface processing (EPD- electrophoretic deposition). The described materials are an alternative to polymer nerve implants e.g. tubes or hydrogels which are already present on the market and applied to regenerate nerves.
