What size features do you want to print and what length nanotube do you need? Are you interested in single wall or multiwall nanotubes? Roger Shile -----Original Message----- Dear all, I heard about some techniques to print out carbon nanotube directly on the substrate. This seems an interesting process to me and I am wondering if any of you have experience on this. Is there company can handle this sort of printing? Thanks and happy valentine's day!
