Carbon material-based nanopatterns and nanostructures: Synthesis, characterization and applications

Summary form only given. In this talk, I will summarize the recent research on carbon nanotubes (CNTs) and graphene-related materials done in my group. It includes the dip-pen nanolithography-based controlled fabrication of CNT arrays on solid substrates, "needle-scratching" method based fabrication of large-area catalyst patterns used for growth of ultralong (0.5 mm) and high density single-walled CNTs (10 tubes/μm), synthesis of grapheme derivative-based materials, and the graphene derivative-based chemical and bio-sensing, solar cells, devices and cell cultures.
