Effect of Sm-Au on Silver Staining Results and it ́s UV-Vis Absorption Spectrum

Abstract:

Sm particles and gold nanoparticles were prepared respectively. Effects of Sm-Au particles on silver staining results were studied, and UV-Vis absorption spectrum of Sm-Au particles solution was studied. Time and color of sport with Sm-Au particles is longer and darker than that of with gold nanoparticles. The time of sport with Sm-Au particles is as long as 28.5 min, which is 2.6 times as long as with gold nanoparticles. Although amount of gold nanoparticles reduced 80%, the color of sport with Sm-Au particles is darker than that of with gold nanoparticles. In 200.00-800.00 nm, Sm particles solution and gold nanoparticles solution has one absorption peak, respectively, and λ_max is 276 nm, 521 nm respectively. Sm-Au particles solution has two absorption peaks, λ_{max (Sm)} and λ_{max (Au)} are 276 nm and 523 nm respectively. λ_max of Sm particles is constant, and λ_max of Au nanoparticles occurs red moving. Sm particles and gold nanoparticles may have interaction.
