Summary:Tip‐Enhanced Raman Scattering In article number 2301841, Shuichi Toyouchi, Yasuhiko Fujita, Hirofumi Tanaka, and co‐workers perform a nano‐Raman analysis of single graphene nanoribbons prepared by chemical unzipping of double‐walled carbon nanotubes. Super‐resolution silver nanowire‐based tip‐enhanced Raman scattering microscopy reveals a large difference in defect density between inner/outer nanotube‐derived ribbons, as well as the randomness of edge structures upon unzipping reaction.
