Nanotechnology has been advanced since the last decades. Among all nanomaterials that have been developed, nanosilver is the most frequently used nanoparticles. Its release into natural water bodies is inevitable due to its broad applications. Nanosilver (nAg) was prepared via Tollens method using. The morphology, size distribution and average size of the obtained nAg was characterized using Tr...
background: bovine mastitis is the most costly disease in dairy cows and causes significant decrease in milk production. this disease is one of the main reasons of antibiotic therapy in dairy cows. objectives: staphylococcus aureus is counted as a major pathogen associated with the outbreaks of mastitis in dairy herds. therefore, the purpose of the present study is to examine the antibacterial ...
the aim of this study was to assess the meat quality attributes of broiler chickens fed diets supplemented with silver nanoparticles coated on zeolite. a total of 375 one-day-old broilers was assigned in a completely randomized design to 1 of 5 treatment groups including: basal diet, basal diet supplemented with 1% zeolite, and basal diet supplemented with one of the three levels of zeolite coa...
objective: nanosilver has numerous applications in medicine due to its potent antibacterial activity. however, data regarding the bio-safety of its effective concentrations is scarce. this study aims to assess the toxicity of silver nanoparticles on human gingival epithelial cells under in-vitro conditions. methods: this in vitro study evaluated the toxic effects of filtered and unfiltered na...
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...
objective(s): nanosilver is one of the most widely used nanomaterials due to its strong antimicrobial activity. thus, because of increasing potential for exposure of human to nanosilver, there is an increasing concern about possible side effects of these nanoparticles. in this study, we tested the potential dermal toxicity of nanosilver bandage on serum chemical biomarkers in mice. materials a...
Nanosilver has recently been recognized as an antimicrobial agent. Although this nanoparticlecan be used in medical applications but its dermal and systemic toxicity via dermal exposure hasnot been completely determined yet. The aim in this study was to investigate the potential dermaltoxicity of Nanosilver in subchronic method. Before the colloidal silver nanoparticle toxicityevaluation, their...
Nanotechnology is a new and specific method for therapy of diseases. Nanosilver particle is one of the functional fields of nanotechnology. It has been shown that these nanoparticles have antibacterial and antifungal properties. Different studied have been shown that nanoparticles may have important role in medicine. For example, it has been shown to have inhibitory effects on the treatment of ...
