Abstract
We report the synthesis of a single-walled carbon nanotube (SWNT) graft copolymer. This polymer was prepared by the functionalization of SWNTs with polyethyleneimine (PEI). We used this graft copolymer, SWNT−PEI, as a substrate for cultured neurons and found that it promotes neurite outgrowth and branching.Keywords
