“…The intrinsic properties of the metal nanostructures can be tuned by controlling their shape, size, and crystallinity. To date, many approaches have been developed to prepare Ag nanostructures in different shapes, like wires [17][18][19][20], belts [21], rice [22], ribbons [23], prisms [24], sheets [25,26], cubes [27], and others [28][29][30][31][32]. Recently, extensive interest has been expressed in the synthesis of more complex hierarchical structures that are ideally composed of nanocrystals (particles, rods, ribbons, sheets, and so forth) arranged in a particular way as well as their growth mechanism.…”

Self-organized silver nanostructures were grown in porous Si/SiO 2 matrix fabricated by ion track technology. The different silver nanostructures with shapes like "sunflowers", "azalea" or "corn" were realized by applying wet-chemical electroless deposition. We show that reproducible self-organized silver "sunflower" like nanostructures provide a high enhanced Raman signal of Nile blue dye molecules. Signal enhancement for a few or even just a single silver "sunflower" is demonstrated by analyzing the surface-enhanced Raman signature of Nile blue dye molecules. According to this, the silver nanostructures can act as efficient surfaces for surface enhanced Raman spectroscopy as well as (bio)-sensor applications.

Design and fabrication of noble metal nanocrystals have attracted much attention due to their wide applications in catalysis, optical detection and biomedicine. However, it still remains a challenge to scale-up the production in a high-quality, low-cost and eco-friendly way. Here we show that single crystalline silver nanobelts grow abundantly on the surface of biomass-derived monolithic activated carbon (MAC), using [Ag(NH3)2]NO3 aqueous solution only. By varying the [Ag(NH3)2]NO3 concentration, silver nanoplates or nanoflowers can also be selectively obtained. The silver growth was illustrated using a galvanic-cell mechanism. The lowering of cell potential via using [Ag(NH3)2]+ precursor, together with the AgCl crystalline seed initiation, and the releasing of OH− in the reaction process, create a stable environment for the self-compensatory growth of silver nanocrystals. Our work revealed the great versatility of a new type of template-directed galvanic-cell reaction for the controlled growth of noble metal nanocrystals.

“…Several methods have been reported for the preparation of AgNBs, including wet chemical 9 10 11 12 13 and electrochemical methods 14 15 16 17 18 . However, these procedures need the simultaneous addition of reducing agents and templates at either high or very low temperatures, which makes controlling the size and morphology of the system more complicated.…”

Silver nanobelts (AgNBs) have attracted a great interest due to their excellent electrical conductivity and mechanical strength, leading a facile synthesis of these AgNBs in great demand. In here, we are reporting a simple, aqueous phase, size tunable synthesis of smooth surfaced 1D-silver nanobelts using a Polyaniline (PANi) derived polymer at room temperature. The specifically designed PANi polymer, comprising a pendant carboxyl group in the chain, acted as both a reducing agent and template. The resulting Ag nanobelts have more than 10 μm of length, mean width values ranging from 41.1 (11.5) nm to 118.5 (8.8) nm and a mean thickness value of 36.7 (12.5) nm. The UV-Visible spectrum of the AgNBs has shown two Surface Plasmon Resonance peaks at 352 nm and 383 nm.
