in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...

A facile one-step polyol method is employed to synthesize the Ag nanoparticles (NPs) in large scale. The Ag NPs with different average diameter (from 52 to 120 nm) and particle size distribution are prepared by changing the mass ratio of AgNO3 and PVP. Furthermore, the as-obtained Ag NPs are prepared as conductive inks, which could be screen printed on various flexible substrates and formed as ...

Continuous formation and utilization of nanoparticles (NPs) have resulted into significant discharge of nanosized particles into the environment. NPs find applications in numerous products and agriculture sector, and gaining importance in recent years. In the present study, silver nanoparticles (AgNPs) were biosynthesized from silver nitrate (AgNO3) by green synthesis approach using Aloe vera e...

We investigate the transformation of single crystal gold nanorod surface morphology over extended growth times. After initial rapid anisotropic growth and disappearance of {111} bridging facets, the aspect ratios converge across AgNO3 concentrations. The surface morphology transitions from faceted to curved. These observations imply the final aspect ratio has little dependence on the AgNO3 conc...

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...

Tupling, R., and H. Green. Silver ions induce Ca2 release from the SR in vitro by acting on the Ca2 release channel and the Ca2 pump. J Appl Physiol 92: 1603–1610, 2002; 10.1152/japplphysiol.00756.2001.—Silver nitrate (AgNO3) is a sulfhydryl oxidizing agent that induces a biphasic Ca2 release from isolated sarcoplasmic reticulum (SR) vesicles by presumably oxidizing critical sulfhydryl groups i...

We have investigated the effects of AgCl and AgNO3 on the Cav3.1 calcium channels stably expressed in the HEK 293 cells. Ca2+ was used as a charge carrier. Both forms of Ag+ blocked the Cav3.1 channel and negatively shifted the I-V relations in a concentration-dependent manner. The inhibition of current amplitude by AgCl was voltage-dependent and increased with increasing amplitude of the depol...

XRD and EDX analyses confirmed the presence of Ag in all coatings deposited using electrochemical method and silver. The mean thickness coating was noted to be highest in EHA/AG group (102.20 4.20 um) followed by PHA (76.40 2.20 um). Mean coating thicknesses in other groups were: PHA/AgNO3 (76.20 1.29 um); EHA (32.98 2.50 um); EHA/ Ag/2-layers (30.70 2.40 um); EHA/AgNO3 (8.60 0.60 um). The aver...

Silver nitrate (AgNO3) is a sulfhydryl oxidizing agent that induces a biphasic Ca2+ release from isolated sarcoplasmic reticulum (SR) vesicles by presumably oxidizing critical sulfhydryl groups in the Ca2+ release channel (CRC), causing the channel to open. To further examine the effects of AgNO3 on the CRC and the Ca2+-ATPase, Ca2+ release was measured in muscle homogenates prepared from rat h...

The mechanisms of toxicity of Ag nanoparticles (NPs) are unclear, in particular in the terrestrial environment. In this study the effects of AgNP (AgNM300K) were assessed in terms of oxidative stress in the soil worm Enchytraeus crypticus, using a range of biochemical markers [catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST), glutathione reductase (GR), total glutat...
