Surprisingly long-range surface-enhanced Raman scattering (SERS) on Au-Ni multisegmented nanowires.
نویسندگان
چکیده
Very long range surface-enhanced Raman scattering is observed from a nickel nanowire that is separated by 120 nm from a pair of gold nanodisks. The excitation of the surface-plasmon resonance (SPR) from the gold nanodisk pair generates an enhanced electromagnetic field near the nickel segment (SEM, left), leading to Raman intensity greater than the nickel alone (right).

Disordered array of Au covered Silicon nanowires for SERS biosensing combined with electrochemical detection
We report on highly disordered array of Au coated silicon nanowires (Au/SiNWs) as surface enhanced Raman scattering (SERS) probe combined with electrochemical detection for biosensing applications. SiNWs, few microns long, were grown by plasma enhanced chemical vapor deposition on common microscope slides and covered by Au evaporated film, 150 nm thick. The capability of the resulting composite...
متن کاملSurface-enhanced Raman scattering of rhodamine 6G on nanowire arrays decorated with gold nanoparticles.
We investigate the surface-enhanced Raman scattering (SERS) of rhodamine 6G (R6G) adsorbed on Au nanoparticles attached to InP nanowires. We find that nanowire arrays act as frameworks for effective SERS substrates with a significantly higher Raman signal sensitivity than a planar framework of Au nanoparticles adsorbed two-dimensionally on a flat surface. The SERS signal displays a clear polari...

We present the synthesis of highly anisotropic nickel nanowires (NWs) and large area, free-standing carpets extending over cm(2) area by simple solution phase chemistry. The materials can be post-synthetically manipulated to produce hybrid tubes, wires, and carpets by galvanic exchange reactions with Au(3+), Ag(+), Pt(2+), and Pd(2+). All of these structures, especially the hybrid carpets and t...

Vertically aligned, high-density ZnO nanowires (NWs) were grown for the first time on c-plane sapphire using binary alloys of Ni/Au or Cu/Au as the catalyst. The growth was performed under argon gas flow and involved the vapor-liquid-solid (VLS) growth process.We have investigated various ratios of catalyst components for the NWs growth and results indicate that very thin adhesion layers of Ni ...

We have demonstrated a surface-enhanced Raman scattering (SERS) substrate capable of detecting 1 pM of benzenethiol (BT) and developed better understanding of its enhancing mechanism by varying the fabrication process and also performing detailed simulation studies. The extreme enhancement originates from the three dimensionally fabricated and optimized substrate, which is made of Au-nanopartic...
