| The intensity ratio of the D and G bands (ID/IG) is commonly used to evaluate the quality of carbon materials. No obvious D band was observed for any of the MWCNTs dispersed on substrates (Supplementary Fig. 6), suggesting the high quality of the starting materials. The average ID/IG values were respectively 0.38, 0.30 and 0.28 for our single-, bi- and trilayer GNRs with 10–20-nm widths.Because defect density on the pristine MWCNTs was low, the D-band Raman signal of our GNRs should be mainly due to their open edges24,25. The ID/IG values were lower than those for GNRs obtained by lithographic etching of pristine graphene sheets (ID/IG was ,2 for a bilayer GNR of,28-nm width obtained by lithographic patterning (X. R. Wang et al., unpublished data); see Supplementary Fig. 5),indicating the high quality of our GNRs, in particular the high degree of edge smoothness. |

| The intensity ratio of the D and G bands (ID/IG) is commonly used to evaluate the quality of carbon materials.D带和G带强度比常常用来评价碳材料的质量。 No obvious D band was observed for any of the MWCNTs dispersed on substrates (Supplementary Fig. 6), suggesting the high quality of the starting materials. 对任何分散在基质中的MWCNTs，均未能观测到明显的D带，提示起始原料良好的质量。The average ID/IG values were respectively 0.38, 0.30 and 0.28 for our single-, bi- and trilayer GNRs with 10–20-nm widths. 我们宽度为10-20nm的单、双和三层GNR的平均ID/IG 值分别为0.38、0.30和0.28。 Because defect density on the pristine MWCNTs was low, the D-band Raman signal of our GNRs should be mainly due to their open edges24,25. 由于原始MWCNT的缺陷密度低，所以我们的GNR的D带拉曼信号主要应该是由于它们开放的边缘。The ID/IG values were lower than those for GNRs obtained by lithographic etching of pristine graphene sheets (ID/IG was ,2 for a bilayer GNR of,28-nm width obtained by lithographic patterning (X. R. Wang et al., unpublished data); see Supplementary Fig. 5),indicating the high quality of our GNRs, in particular the high degree of edge smoothness.这些ID/IG值比由平板印刷蚀刻原始石墨烯片之躯的GNR的ID/IG值要低，提示我们的GNR具有较好的质量，尤其具有高度的边缘平衡度。 |

| D带和G带的强度比通常用来评估含碳材料的质量。从分散的MWCNTs的底物（补充的图表6）上没有发现明显的D带，不能表明原始材料的高质量。平均的ID/IG的比值分别是0.38，0.30，0.28对应于单个的，两个和三个革兰氏阴性菌的10-20纳米的宽度。有缺点的密度在早期的MWCNTs上很低，革兰氏阴性菌的D带的拉曼信号主要归功于它们开放的边缘24，25.革兰氏阴性菌的ID/IG的比值低于这些从原始的石板印刷的已经腐蚀的图表中得到的数据（从图表中获得的ID/IG的比值是2，对于双分子层的革兰氏阴性菌其宽度是28纳米）（X. R. Wang 等未公开的数据）；参看补充的图表5），表明我们的革兰氏阴性菌的高质量，部分是高纯度的边缘光滑度。 |
