Theranostics, 2 (2012), pp. 283-294. CrossRef View Record in 3D Fabrication with integration molding of a graphene oxide/polycaprolactone nanoscaffold for neurite regeneration and
The addition of thermally reduced graphene oxide had a slight effect on thermal stability of the obtained materials. The incorporation of 0.5, 1.0, 2.0 and 3.0 wt% of TRG into a system resulted in increased char residues compared to unmodified PU elastomer. Multilayer integration manufacture of graphene oxide based Graphene oxide is a kind of electrically conductive material with excellent biocompatibility for neural tissue engineering. The combination of laminin modified graphene oxide and polycaprolactone was evaluated in nerve scaffold fabrication. The integration manufacture style created multilayers and microporous structure in the scaffold. The multiple pore alignment
Mar 13, 2020 · For wound healing applications, a scaffold of biocompatible/porous network is crucial to support cell proliferation and spreading. Therefore, -polycaprolactone (PCL) nanofibrous scaffold containing co-dopants of strontium/selenium into hydroxyapatite (HAP) were modified with different contributions of graphene oxide (GO) via the laser ablation Optimization of graphene oxide-modified carbon-fiber Graphene oxide (GO) is a carbon-based material that is easily obtained from graphite or graphite oxide. GO has been used broadly for electrochemistry applications and our hypothesis is that GO coating a carbon-fiber microelectrode (CFME) will increase the sensitivity for dopamine by providing more adsorption sites due to the enhancement of oxygen functional groups.
