the antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. the useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. the aim of this study was to evaluate antibacterial activity properties of silver doped zinc...

The development of the eco friendly procedures makes nanoparticles as the rapidly growing field of nanotechnology. Amongst, the silver nanoparticles have become prominent in the field of medicine to their peculiar antimicrobial properties. In the present study we suggest an eco friendly procedure of extracellular synthesis of silver nanoparticles with an average sizes of 5-50nm using an Act...

interaction of chrysosporium sps. and aspergillus sps. with aqueous agno3 was investigated for synthesis of silver nanoparticles. biological reduction and extracellular synthesis of silver nanoparticles in 28 hour at 270c and ph 5.6 was done. the nanometallic dispersion was characterized by surface plasmon absorbance measuring at 424 – 530 nm for ag nanoparticles. high resolution transmission e...

A simple, inexpensive and one-step synthesis route of Ag-TiO2 nanoparticles by arc discharge method isreported. The resulting nanoparticles were characterized using X-ray diffraction and scanning electronmicroscopy. X-ray diffraction patterns demonstrate dominance of rutile to anatase phase in TiO2 andformation of silver metal on TiO2 after arc discharge process. Scanning electron microscopy im...

background: nanoparticles have become one of the leading technologies over the past two years. the extensive use of nanoparticles has raised great concern about their occupational fate and biological effects. with an increase in the production and use of nanomaterial, it is more likely to get exposed to them occupationally and environmentally. objective: to assess the toxicity of silver nanopar...

background: according to the recent studies, the antibacterial activities of silver nanoparticles (ag-nps) were studied on gram-positive staphylococcus aureus and gram-negative escherichia coli. in this study antibacterial effect of silver nanoparticles that used for coating textiles, on e.coli and s.aureus was investigated. methods: silver nanoparticles were coated on textile fabric by corona ...

In the present study, we have reported the biological synthesis of silver nanoparticles (AgNPs) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (PBW343, Triticum durum and Aegilops tauschii )for the reduction of silver ions to silver nanoparticles. Bioreduction of Ag+ to Ag0 was observed when aqueous extract augmented with silver nitrate (AgNO3) was incubated ...
