Synthesis of colloidal crystals of controllable thickness through the Langmuir-Blodgett technique
Stéphane Reculusa,Serge Ravaine +1 more
TL;DR: In this article, the Langmuir−Blodgett technique was used to control the sample thickness at the layer level whereas the overall crystal quality should be good enough for use in several applications.

Surface-enhanced Raman scattering of methylene blue adsorbed on cap-shaped silver nanoparticles
Gui-Na Xiao,Shi-Qing Man +1 more
TL;DR: In this paper, the surface-enhanced Raman scattering (SERS) activities of these nanoparticles were investigated using methylene blue (MB) as a probe molecule, and the enhancement factor was estimated to be as large as 4.2 × 10 7.
