Insight into the fabrication and perspective of dendritic Ag nanostructures

Abstract

This article reviews recent advances in the shape-controlled synthesis routes of hierarchical Ag dendritic nanostructures. Various fabricated techniques, with or without templates or surfactants, electrochemical method and sonochemical, microwave or photochemical assisted synthesis method, can be amazingly effective in the dendritic Ag nanostructures synthesis, if synthetic parameters are carefully selected. The involved synthesis mechanism are discussed in order to control the limited factors along the fabricated progress efficiently and then to find new synthetic means. Also, the blemish of the above synthesis routes that hinders the practical application is pointed out to inspire the future research.

Silver/silver chloride (Ag/AgCl) nanoparticles synthesized from Azadirachta indica lalex and its antibiofilm activity against fluconazole resistant Candida tropicalis

“…Electron microscopy analyses revealed the morphology, shape and size of the synthesized nanoparticles, the present study clearly shows that the triangles, tetragons, pentagons and hexagonal structure with a size range of 35-60 nm. The present study of SEM analyses exhibits dendrite-like structures, which is similar with those described by Cai et al (2017) [40] who demonstrated that the small silver nanoparticles were attached on the surface of large silver chloride (AgCl) nanoparticles. The SEM analysis shows the dendritelike silver nanoparticles on the surface of the silver chloride nanoparticles, suggesting successful silver nanoparticles synthesis using neem latex.…”

Electrochemical deposition of flower-like nanostructured silver particles with a PVA modified carbon cloth cathode

“…This is possibly because the growth of silver crystals is dominated by the diffusion of silver ions, resulting in the formation of dendritic structure, which is in good agreement with the diffusion-limited aggregation (DLA) model. 42,43…”

“…This is possibly because the growth of silver crystals is dominated by the diffusion of silver ions, resulting in the formation of dendritic structure, which is in good agreement with the diffusionlimited aggregation (DLA) model. 42,43 The ower-like structure has two morphological characteristics of akes and owers at the same time. Through the above analysis, it was found that the deposited silver morphology changed from typical dendritic shape, and then to ower-like shape with the current density decrease.…”

Robust and cost-effective silver dendritic nanostructures for SERS-based trace detection of RDX and ammonium nitrate

“…[21][22][23][24][25] Among the various AgNSs, silver nanodendrites (AgNDs) have a pronounced structure that offers many advantages, as their abundant trunks and branches provide scope for a large number of hotspots, which can boost the detection capability and sensitivity. [26][27][28][29] Ag dendrites can be prepared by an electroless deposition process (or galvanic displacement), which is a streamlined wetting process that utilizes a solid reducing agent, such as a silicon wafer, copper plate, aluminium foil, and zinc templates, to name a few. [30][31][32][33] A silicon wafer can be utilized as a reducing agent due to its compatibility, and wellunderstood chemical and physical properties.…”
