“… 25 In particular, triangular silver nanoplates were always selected as the spectrophotometric nano-reagent in the areas of the chemical analysis and optical sensors. 26 Extensive studies have been evidenced that triangular silver nanoplates have a promising application to selectively detect some kinds of volatile compounds, e.g. chlorides.…”

“…Such Ag NCs have been used to localized surface plasmon resonance (LSPR) sensor, surface enhanced Raman spectroscopy (SERS), light management in optoelectronic devices, and templates for hollow structures . Due to the intensive studies, the shape controlled Ag NCs such as nanospheres, nanocubes, nanobars, nanoplates, and nanowires were successfully synthesized by polyol solution chemistry. Among them, the Ag nanocubes have attracted great attention because they can be used as a sacrificial template for hollow Au nanostructure, which can be used as a sensor and a container due to controllable LSPR peaks near infrared region, and a useful substrate for SERS sensing …”

Uniform Ag nanocubes are reproducibly synthesized by a AgCl particle‐mediated heterogeneous nucleation and disassembly process in polyol chemistry. By introducing N,N‐dimethylformamide (DMF) in a conventional polyol method with HCl etchant, Ag nanocrystals (NCs) begin to be nucleated on the surface of AgCl‐precipitated particles due to the promoted reduction reaction by DMF. The nucleated Ag NCs on the AgCl particles are grown to Ag nanocubes in shape by consuming Ag sources from the AgCl mother particles. Eventually the grown Ag nanocubes are disassembled from the mother AgCl particles because the AgCl particles are fully digested by the growing Ag nanocubes. Density functional theory calculation confirms that the Ag atoms can be favorably deposited on the (100) facet of AgCl particles and the Ag nuclei on the AgCl particles tend to reveal (100) facet.

“…[27] Strategies based around nanomaterials have drawn particular attention. [28] These include a series of articles indicating that the detection of Hg 2 + can be achieved by the loss of colour from AgNPs stabilized by citrate, [29] p-phenylenediamine, [30] cysteamine, [31] PVA [32] and a range of biologically derived compounds [33] with the bleaching of the plasmonic resonance attributed to the selective reduction of Hg 2 + by the Ag nanoparticle and potentially amalgamation with the nanoparticle surface. Hg 2 + has also been detected through fluorescent enhancement with a AgNP bound rhodamine B derivative.…”

Modified silver nanoparticles with a self‐assembled disulfide functionalized 2,2'‐bipyridine (L1 and L2) monolayer, and the corresponding rhenium complex [Re(L2)(CO)3Br] are shown to provide a method to position the nanoparticles at a water/dichloromethane interface forming a lustrous metal‐like‐liquid film (MeLLF) with a unique SERS response. The film formed using L2 showed divergent behaviour in the presence of a range of metal ions whilst bound to the surface. [Re(L)(CO)3Br] (where L=2,2'‐bipyridine, L1 and L2) in solution demonstrates a selective interaction with Hg2+, observed by UV‐vis, emission and 1H NMR spectroscopy, attributed to abstraction of the bromide. This interaction was demonstrated by subtle changes in the characteristic Raman Re‐CO stretch at 510 cm−1 both with the MeLLF, and when the film is immobilized in a PVA surface‐exposed‐nano‐sheet (SENS). The work provides proof of concept that the organometallic complexes can be employed as “labels” to generate SERS‐active nanoparticle films that possess detection capabilities.
