Silver nanorods (Ag NR) have been successfully synthesized by wet chemical method (seed-mediated growth) utilizing 10 nm silver nanospheres as a seed material and subsequent reduction of silver precursor with a weak reducing agent (ascorbic acid) along with a directing surfactant. The effect of synthesis temperature on the structure, morphology, composition and optical properties were investiga...

Metal conductive ink for flexible electroncs has exhibited a promising future recently. Here, an innovative strategy was reported to synthesize silver nanocolloid (2.5±0.5 nm) and separate solid silver nanoparticles (<10 nm) effectively. Specifically, silver nitrate (AgNO3) was used as a silver precursor, sodium borohydride (NaBH4) as a reducing agent, fatty acid (CnH2n+1COOH) as a dispersant a...

Mature-green tomato fruit (Lycopersicon esculentum Mill.) were treated asymmetrically with 2 millimolar silver thiosulfate (STS) through a cut portion of the peduncle while still attached to the plant. One-half of the fruit received silver and remained green while the other half ripened normally and was silver-free (less than 0.01 parts per billion). Harvested mature-green fruit were also treat...

Developing reliable and eco-friendly processes for the synthesis of metallic nanoparticles is an essential step in the field of application of nanotechnology .Using natural factories such as biological systems is a way of developing such processes. Nowadays, the synthesis of silver nanoparticles is very common due to its numerous applications in different fields. The synthesis of these nanopart...

Age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. Methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. The cells had greater affinity for diamine silver compared to methenamin...

It has been suggested that the nature of dendritic cells in the corneal epithelium is a melanocyte of neural crest origin, but no cytochemical evidence is yet available.' Recently, it has been reported by Mishima and co-workers that an ammoniated silver nitrate stain, modified for use in electron microscopy, produces a highly selective metallic deposit not only in melanin granules but also in c...

In this research, silver nanoparticles (AgNPs) were synthesized in chitosan (Cts), Cts/gelatin and gelatin suspensions using a chemical reducing agent. Cts and gelatin were used as natural stabilizers and solid support, whereas AgNO(3) was used as the silver precursor. Sodium borohydride (NaBH(4)) was used as the reducing agent. The properties of AgNPs in Cts, Cts/gelatin and gelatin bionanocom...

A new and promising biosurfactant extracted from corn steep liquor has been used for the green synthesis of gold and silver nanoparticles (NPs) in a one-step procedure induced by temperature. Most of the biosurfactants proposed in the literature are produced by pathogenic microorganisms; whereas the biosurfactant used in the current work was extracted from a liquid stream, fermented spontaneous...

A novel method of integration a silver-polydimethylsiloxane (PDMS) nanocomposite in microfluidic channel for the realization lab-on-a-chip is reported this work. By using silver nitrate aqueous precursor solution, nanostructures are formed on, and under surface PDMS, by situ reduction. The aggregates reduction have wide absorbance plasmon band UV–Visible range. Separated nano-islands, having na...
