Аннотация: The significant growth in applications of silver nanoparticles across -various branches of industry as well as in consumer products has caused concerns that nanosilver may have a toxic effect on the environment and human health and may have implications for eco-terorism. This paper presents research on antimicrobial effects of silver nanoparticles. We studied the cytotoxicity of silver nanoparticles via an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) assay that measures cell activity through the mitochondrial cleavage of a molecule that exhibits a change of colour that can be measured spectrophotometrically. NIH-3T3 (Swiss mouse embryo), HEP-G2 (human hepatocellular carcinoma), A-549 (human lung carcinoma), PC-12 (rat adrenal pheochromocytoma), and Colo-320 (human colon adenocarcinoma) cells were chosen in order to study different possible absorption paths of nanoparticles into the organism and various areas of particle accumulation in the body. The obtained MTT test results have shown that silver nanoparticles with concentrations of ∼1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. © Springer Science+Business Media B.V. 2011.

Аннотация: Antimicrobial and antifungal properties of silver nanoparticles, silver ions, acrylate paint and cotton fabric impregnated with Ag nanoparticles were assessed against Escherichia coli (Gram-negative bacterium); Staphylococcus aureus and Bacillus subtilis (Gram-positive bacteria); Aspergillus niger, Aureobasidium pullulans and Penicillium phoeniceum (cosmopolitan saprotrophic fungi). The silver ions used in the bacterial susceptibility tests were released from pure silver electrodes using a 12 V battery-operated direct current generator. The water-based silver colloidal solution was obtained by electroreduction of silver ions in water. Nanosilver was less effective against E. coli, S. aureus, B. subtilis and P. phoeniceum compared to silver ions. However silver nanoparticles have prolonged bactericidal effect as a result of continuous release of Ag ions in sufficient concentration and thus nanoparticles can be more suitable in some bactericidal applications. The synthesized silver nanoparticles added to water paints or cotton fabrics have demonstrated a pronounced antibacterial and antifungal effect. В© 2011 Springer Science+Business Media B.V.

Аннотация: The minimum inhibitory concentrations (MICs) assays conducted for E. coli, S. aureus, B. subtilis and P. phoeniceum have shown that the antimicrobial activity of silver ions was superior to that of silver nanoparticles. As silver nanoparticles can be more suitable in some bactericidal applications than silver ions, the efficacy of nanosilver as an antimicrobial agent against a range of microbes on the surface of water paints and cotton fabrics has been studied. The cytotoxicity of silver nanoparticles has been studied using NIH-3T3, HEP-G2, A-549, PC-12, and Colo-320 cells via the MTT ((3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) test. The MTT test results obtained have shown that silver nanoparticles in concentrations of ~1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. However, silver nanoparticles as a commercially viable addition to be used in paint and textile industry are unlikely to present a direct health risk. © 2010 Nova Science Publishers, Inc.

Аннотация: The growth of bacteria and fungi on a nanofiltration (NF) membrane is known to reduce its permeability and lifetime and increase overall energy use. Over the last decade, application of silver nanoparticles (AgNPs) has shown to present a strong potential in preventing biofouling of NF membrane processes. The paper deals with a novel facile method developed to in situ incorporate nanosilver stabilized with the polyhexamethylene biguanide hydrochloride (PHMB) onto the commercial NF membrane surface. The scanning electron microscopy (SEM) investigations confirmed a uniform distribution of AgNPs on the surface of NF membrane although AgNPs tend to agglomerate into nano-sized colloidal clusters. Our results showed that AgNPs had little impact on the performance of the NF membrane, including salt rejection and water permeation properties. To evaluate the antibacterial properties of nanocomposite membranes, a "time-kill" analysis, a microbiological technique for measuring the change in a population of microorganisms under the impact of a specific sample, has been used against representatives of Gram-positive and Gram-negative bacteria. Inductively coupled mass spectrometry (ICP-MS) was used to study kinetics of Ag release from modified NF membrane. Leaching rates of Ag were low that will possibly result in long-established antimicrobial and antifungal properties. The present research offers a potential for its further use as a new type of modified NF membrane mitigating biofouling.
