Research progress on graphene three-dimensional neural scaffold of Suzhou Institute of Nanotechnology, Chinese Academy of Sciences Graphene is a low-dimensional carbon nanomaterial composed of a single layer or few layers of carbon atoms. It has excellent physical and chemical properties and has rapidly become a material science and condensed state since its discovery in 2004. Research frontiers in physics and other fields. At the same time, graphene exhibits good biocompatibility, and its application in the field of biomedicine has received much attention in recent years. It has been successfully used in cell imaging, drug delivery, stem cell engineering, and tumor treatment. The team of Cheng Guosheng, a researcher at the Institute of Nanotechnology and Nanobionics, Chinese Academy of Sciences, used cell biology and materials science to systematically study the effect of two-dimensional graphene films on the development of hippocampal neuronal cells, and found that graphene not only has good effects on nerve cells Biocompatibility, and has a significant role in promoting neurite outgrowth and growth (Biomaterials 2011, 32, 9374-9382). The research group also carried out the functional modification of bioactive molecules on the surface of graphene, and quantitatively analyzed the effect of the adsorption of active molecules on the interaction of graphene sheets (Carbon 2013, 51, 164-173). Recently, the research team of Cheng Guosheng team cooperated with Dai Jianwu team of Institute of Genetics and Development, Chinese Academy of Sciences, and successfully developed a new type of graphene foam for use on the basis of the three-dimensional porous carbon material work reported by the research group of Shenyang Metal Institute of Chinese Academy of Sciences Neural stem cell scaffold materials, and systematically studied the interaction between graphene scaffolds and neural stem cells. The results showed that the three-dimensional graphene scaffold not only promoted the proliferation of neural stem cells, but also induced the differentiation of neural stem cells into functional neurons to a certain extent. Further, using the good electrical conductivity of graphene carbon material, in situ electrical stimulation of neural stem cells was induced to induce differentiation, and a reversible calcium ion oscillation response was obtained. The work was recently published in Scientific Reports (2013, 3, 1604), focusing on the application potential of three-dimensional graphene structures in the field of neural tissue engineering and neural stem cell transplantation therapy. At present, in-depth research is being carried out on the three levels of in vitro and in vivo neuron synapse formation, nerve signal transmission, and repair of damaged nerve cells on the three-dimensional graphene scaffold. The research was supported by the 973 project of the Ministry of Science and Technology, the Pilot Project of Stem Cells and Regenerative Medicine of the Chinese Academy of Sciences, and the International Cooperation Project of the National Natural Science Foundation of China.
