Strong surface enhancement Raman spectroscopy signal of 4-aminothiophenol on silver substrate prepared by controlled electrodeposition is documented in this article.Enhancement factor was found to be affected not only by nanoparticle size,shape,orientation and spatial distribution,but also by interaction of ...
The electrochemical technique and in situ Fourier transfer surface enhanced Raman spectroscopy were employed to investigate the electrochemical transformation processes of4-aminothiophenol(PATP) on Au electrode in an acidic solution. 采用循环伏安法和表面增强拉曼散射现场研究了酸性溶液中4-氨基苯硫酚(PATP)在...
Halloysite nanotubes loaded with 4-aminothiophenol capped silver nanoparticles (mHNTs-AgNPs4−ATP) composite was synthesized as a sensitive surface-enhanced Raman scattering (SERS) probe for the determination of nitrite ions in sausage and pork luncheon meat. The as-prepared composite was characterized...
4-aminothiophenol molecules, used as the Raman reporters, were placed between the Au core and the Ag shell. The dependence of Raman intensity on the inside/surface location of the reporter molecules was studied. The interior molecules showed a strong and uniform Raman intensity, at least an ...

We investigated the catalytic activity of Au nanoparticles with different morphologies as surface-enhanced Raman scattering substrates for the conversion of p-aminothiophenol to p,p'-dimercaptoazobenzene. The experimental results indicated that the order of catalytic activity is nanorod> nanoplate> ...
Surface plasmon assisted catalysis (SPAC) reactions of 4-aminothiophenol (4ATP) to and back from 4,4'-dimercaptoazobenzene (DMAB) have been investigated by single particle surface enhanced Raman spectroscopy, using a self-designed gas flow cell to control the reductive/oxidative environment over the...
This study employed the surface-enhanced Raman scattering (SERS) enhancement property of 4-aminothiophenol (4-ATP) as a signal turn off approach functionalized on AgAu alloyed nanoparticle to firstly detect Hg in standard solutions and spiked tea samples. Different chemometric algorithms were applied ...
