  • Patent number: 10774227
    Abstract: The present invention relates to preparation and use of nanocellulose fibrils or crystals such as disintegrated bacterial nanocellulose, tunicate-derived nanocellulose, or plant-derived nanocellulose, together with carbon nanotubes, as a biocompatible and conductive ink for 3D printing of electrically conductive patterns. Biocompatible conductive bioinks described in this invention were printed in the form of connected lines onto wet or dried nanocellulose films, bacterial cellulose membrane, or tunicate decellularized tissue. The devices were biocompatible and showed excellent mechanical properties and good electrical conductivity through printed lines (3.8·10?1 S cm?1). Such scaffolds were used to culture neural cells. Neural cells attached selectively on the printed pattern and formed connective networks.
