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 ...

background and objectives:plant essential oils are sometimes considered for use as antimicrobial agents in foods and medicines and they could be combined with other antimicrobial agents to strengthen the effect and/or reduce the required dose. this study was conducted to determine the chemical composition of the ocimum basilicum, salvia officinalis and trachyspermum ammi essential oils and eval...

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: the application of natural compounds including green tea extract (gte) in food and pharmaceutical industries is limited. encapsulation in nanoliposomes could be used as a delivery system to protect these compounds during processing and storage. objective: in this study encapsulation of green tea extract in nanoliposomes and evaluation of its antibacterial, antioxidant and prebiotic ...

Kombucha is sweetened black tea that is fermented by a symbiosis of bacteria and yeast embedded within a cellulose membrane. It is considered a health drink in many countries because it is a rich source of vitamins and may have other health benefits. It has previously been reported that adding lactic acid bacteria (Lactobacillus) strains to kombucha can enhance its biological functions, but in ...

non-steroidal anti-inflammatory drugs (nsaids) have shown antibacterial activity in some recent studies. the aim of this study was to evaluate the antibacterial effect of diclofenac against enterococcus faecalis (e. faecalis) as a resistant endodontic bacterium in comparison with ibuprofen, calcium hydroxide and amoxicillin.the antibacterial activity of materials was evaluated using agar diffus...

The present study was conducted to estimate in-vitro antimicrobial activity of six herbal plant extracts (Black pepper, Fennel, Turmeric, Black cumin, Ginger, Bay leaf) by using well diffusion method. It determined that both methanolic and ethyl acetate these additives possessed considerable antibacterial against Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris, Salmonella typhi ...

objectives the aim of this study was to evaluate the stability of antibacterial properties of nanosilver solution during a period of 9 months against streptococcus mutans, staphylococcus aureus and pseudomonas aeruginosa. materials and methods in this in vitro study, the antibacterial effect of serial concentrations of nanosilver solution and amoxicillin antibiotic as control group on the stand...

nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study  cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

in this study, zinc oxide nanoparticles (znonps) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of staphylococcus aureus was studied. the zinc oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen s.aureus. the nanoparticles size and shapes were characterized by transmission electron m...
