Surface-enhanced Raman scattering studies on aggregated silver nanoplates in aqueous solution
Article Abstract:
Synthesis of four different sizes of citrate-protected silver nanoplates with the corresponding in-plane dipole resonance band at 530, 619, 778, and 858 nm, respectively is performed for surface-enhanced Raman scattering (SERS) study. Results reveal that a market red shift of the in-plane dipole resonance of silver nanoplates is observed, whereas their other resonance modes only have small alterations in the site or intensity during the aggregation process.

Dendron-like growth of silver nanoparticles using a water-soluble oligopeptide
Article Abstract:
A dendron-like nanostructure of silver is grown in solution by using a water-soluble tetrapeptide Tyr-Aib-Tyr-Val (Aib, alpha-amino isobutyric acid), silver nitrate and methonal. The optical absorption spectra is analyzed by Mie scattering theory, which shows that there is a metal-nonmetal transition in silver particles having diameters less than ~2.0 nm.
