Schematic diagram depicting the directed growth of MSCs on large-scale carbon nanotube patterns. a patterning of non-polar 1-octadecanethiol (ODT) SAM while leaving some bare Au area. b Selective adsorption and precision alignment of CNTs directly onto a bare Au surface. c Passivation of the exposed bare Au surface between the aligned CNTs with ODT. d Directed growth of MSCs onto the carbon nanotube patterns [85]
