The formation of spherical gold nanoparticles in the film has been confirmed by the X-ray structural ...
Gold nanoparticles in the multilayer enhance the Raman spectra of the polyelectrolyte multilayers, in contrast with the weak Raman signal, which was observed for normal capsules. High-resolution surface Raman imaging was performed by controlling the filling factor. 展开 ...
Nanoparticles of gold and silver can be made by the reduction of a positively charged metal salt to the zero oxidation state of the pure metal using a reducing agent such as citrate or borohydride. A reproducible and easily prepared method of preparing gold and silver surfaces is to prepare ...

As metallic colloidal nanoparticles that enhance these vibrational signatures, including hydroxylamine–reduced-silver colloids, can be fabricated at large scale under routine conditions, we anticipate that digital (nano)colloid-enhanced Raman spectroscopy will become the technology of choice for the reliable...
Summary This chapter shows that nanoparticles (NPs) and nanostructures can play a key role in developing the new shell-isolated mode for characterizing various electrochemical systems. Shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) has overcome the long-standing material-specific and morp...
Gold nanoparticles (GNPs) were deposited on the surface of graphitic carbon nitride (g-C3N4) via an in situ reduction method using either sodium borohydride or trisodium citrate as the reducing agent. The corresponding hybrid Au/C3N4nano... J Yan,Y Xiao,X Liang,... - 《Jpn.j.appl.phys》...
