These days, electron devices demand high performance electrode. Silver nanowire is the most promising candidate because it has excellent electrical property, however, the process of AgNW synthesis is complicated and it is difficult to obtain long-scale AgNWs in traditional methods. M13 virus is a helical structured biomaterial with 6.6nm of the diameter and 880nm of the length. M13 virus can be modified the chemical properties through genetic engineering method. In this work, we fabricated ultra long-scale AgNW using genetically engineered M13 virus. We observed that the crystallinity of AgNW was affected as changing the engineered chemical structure on major coat protein of M13 virus. The range of AgNW was around 40nm to 250nm and the average length and diameter were around 90um and 1um, respectively. The maximum length of AgNW that was observed was 350um. The existence and morphology of Ag nanoparticles and nanowires were confirmed by FE-SEM and high resolution TEM. |
