TL;DR: Gold-silver alloy nanocages with controllable pores on the surface have been synthesized via galvanic replacement reaction between truncated Ag nanocubes and aqueous HAuCl4 using poly(vinyl pyrrolidone) (PVP) as capping agent.

TL;DR: This paper describes the fastest route to monodispersed silver nanocubes by adding a trace amount of sodium sulfide or sodium hydrosulfide to the conventional polyol synthesis, which was significantly shortened from 16-26 hours to 3-8 minutes.

TL;DR: In this article, a simple route to Ag nanoplates by slowing the polyol reduction of silver nitrate with polyacrylamide (PAM) was described, where the amino groups of PAM can form complexes with Ag+ ions in the solution to substantially reducing the reduction rate, leading to the formation of thin Nanoplates.

TL;DR: In this article, the surface-enhanced Raman scattering (SERS) activities of Ag nanocubes were compared with respect to both size and shape (i.e. sharp vs. truncated) using 514 or 785 nm lasers.

TL;DR: The time scale for energy relaxation was found to increase with the size of the particles, with the relaxation time being independent of the laser intensity, and the period of the coherently excited vibrational mode is proportional to the dimensions of the nanocages.
