the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...
The European Commission should be regulating nanosilver, not asking for yet another report on its impact on health and the environment.
Introduction: Nanosilver particles are one of the functional grounds in nanotechnology field. These nanoparticles may produce free radicals and destruct different cells. In this study, Nanosilver toxic effects on RBC and WBC numbers in male Rats were studied. Thus, male rats were treated with nanosilver and RBC and WBC were detected. Methods: In this study, RBC was detected in male Wistar rats...
Background and Objectives :Microorganisms including Fungi, are among air-transmitted infectious agents at hospitals and patient care settings, which in addition to patients, can afflict Health Care Workers (HCWs) and visitors, and may results in extravagant economic burden and impact on human health. Use of nanotechnology and especially nanosilver particles is one of the methods which are used ...
Metal nanosolicoparticles are suspected to cause diseases in a number of organisms, including man. In this paper, we report the effects of nanosilver (Ag, 1-20 nm particles) on the early development of the zebrafish, a well-established vertebrate model. Embryos at the midgastrula stage were exposed to concentrations ranging from 100 to 0.001 mg/L to verify the effects on different endpoints: le...
b ackgro un d : the antimicrobial activity of silver nanoparticles has been investigated in medical fields in recent years, but there are few studies regarding its effect on oral microorganisms. the aim of the present study was to evaluate the in vitro antimicrobial and toxicity properties of nanosilver against two dental plaque microorganisms and human gingival fibroblast (hgf) cell line. me ...
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...
in this study, microball nanosilver was produced with dimensions of about 1 micrometer in order to reduce the risks of absorption of nanosilver particles through skin and inhalation. different concentration levels of silver have been used in making of hand-sheets. the antibacterial properties of all hand-sheets were evaluated again escherichia coli and bacillus subtilis bacteria. results indica...
Background: The current type of nanoparticle that attracts a lot attention in the pharmaceutical field is Nanosilver because it can act as an antimicrobial. Objective: aim this study was to obtain gel preparation from katuk leaf extract, which effective antibacterial agent against acne. Methods: Katuk extract remains reducing synthesis using green method. characterization performed PSA, FTIR an...
Background: Biosynthesis of nanoparticles has attracted the attention of the scientific community in nanotechnology and biotechnology due to their extensive application in the area of material sciences and medicine. Nowadays, despite a various application of nanomaterial’s, there is a little information about their impact on human health. In this study, we investigated the comparative study on ...
