Outline of Final Research Achievements

We report on a facile method for preparing fluorescent carbon nanowires (CNWs) with pyrolysis of highly aligned DNA nanofibers as carbon source. Silver nanoparticles (AgNPs)-doped CNWs were also produced using pyrolysis of
DNA nanofibers with well-attached AgNPs, indicating emission enhancement assisted by localized plasmon resonances. Furthermore, surface enhanced Raman scattering (SERS) imaging of AgNPs-doped CNWs revealed the generation of
carbonization involved in pyrolysis process of DNA molecules.
