The cyclic voltammetry of both bulk manganese sulfate (BMS) and nano manganese sulfate (NMS) were studied using 0.1M KCl supporting electrolyte and glassy carbon working electrode. The redox behavior for both bulk (BMS) and MnSO4 (NMS) sulfate was studied voltammetrically in presence and absence of Doxorubicin (DR) using three electrodes system, silver- silver chloride (Ag/AgCl), pla...

Abstract: Background and objectives: Antibiotic resistant to Antimicrobial agents is one of the most important concern in hospitals, which can lead to increased costs, treatment fails and mortality rates. The aim of this study was identification of Gram-negative bacilli resistant to extended-spectrum β-lactamase Enzymes (ESBLs) and determination of the effect of silver nanoparticles on the...

The redox behavior for bulk and nano silver nitrate (NSN) were studied by cyclic voltammetry technique in absence and presence of cefdinir antibiotic (CFD) using glassy carbon electrode (GCE) in 0.1 M KNO3 as supporting electrolyte at two different temperatures. Scan rates were studied for the redox reactions of bulk and nano silver nitrate (NSN) in absence and presence of cefdinir antibiotic (...

Silver sulfadiazine is used to prevent and treat infections of second- and third-degree burns. It kills a wide variety of bacteria. In this study silver sulfadiazine was used in gelatin based electro-spun nano-fibers with various drug to polymer ratios (0, 5, 10, 15 and 20 %). SEM, EDX and FTIR analysis showed that the continuous, bead-free, fine fibers containing silver sulfadiazine as an anti...

The synthesis, characterization and application of biologically synthesized nanomaterials have become an important branch of nanotechnology. In this paper, we report the synthesis of highly dispersed silver nanoparticles using a dried stem bark of Boswellia ovalifoliolata. Bark extract as the reducing agent and tested the effect on seed germination and seedling growth. After exposing the silver...

Tumor growth is characterized by uncontrolled cell division. For centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional Iranian and Pakistani medicine for the treatment of melanoma and breast cancer. We have found that these nanocomposite particles are similar to silver nanoparticles (AgNps) in size and shape and that there are so differenc...

The aim of the study was to analyze how per os application of hydrocolloids of silver nanoparticles (22 nm) and lipid-coated silver nanoparticles (5 nm) affect the immune, redox, and lipid status of the blood of broiler chickens. The experiment was conducted on 60 chickens. The first group was the control (Group C). The chickens in Group II received a silver nanoparticle hydrocolloid (Ag-nano) ...

  Background: Precise determination of organic load is one of the major and important parameters in selecting appropriate treatment process for industrial and domestic wastewaters . Performing chemical oxygen demand (COD) test in real samples is always subject to interferences, insufficient sample digestion and consuming high levels of chemical pollutants. The main aim of this scientific and ap...

Silver metal was recovered primarily from spent X-ray photographic solution using a horizontal tube furnace. The X-Ray Diffraction (XRD) spectroscopy analysis approved almost 95 percent purity of the recovered silver metal. In the next step, the synthesis of silver nanoparticles from the recovered silver metal proceeded by using chemical reduction method. The proposed method uses e...
