“…The mechanisms for the antimicrobial behavior of metal/polymer nanocomposites based on thermoplastic matrices explained by the adsorption of bacteria on the polymer surface that cause water to be diffused through the polymer matrix leading to corrosion processes and release of metal ions and water that dissolved in oxygen to the metal/polymer nanocomposite surface causing destroy bacterial membrane 25,50,47,51,30 . The morphological changes and disruption of the bacterial cell membrane of copper oxide nanoparticlen treated bacteria was supported by SEM analysis as seen in Fig.8, the tested bacteria strains coli O157:H7, and methicillinresistant Coaggulase -ve S. aureus , as it find the way into the bacterial cells causing great lipid bilayer and membrane protein damage as reported in previous studies 9,10,11,24,52,53,54 .…”

“…Nanotechnology is an important research field concerning with the manipulation and design of small particles, in the range of 100 nm or less called nano particles [2][3][4] that showed a wide range of properties which differ from its bulk material as electrical, optical, magnetic, catalytic and biological activity as they exhibit a wide range of anti-microbial activity against different species of Gram-negative, Gram-positive bacteria and fungi [5][6][7] . Metal nano particles (NPs) as (NiO, CuO, Sb 2 O 3 and ZnO,) have been subjected of research interest in the last few years especially CuO NPs which gained great attention of researchers due to its potential industrial uses as catalytic process, gas sensors, solar cells and super conductors 1,8 , also its application in wound dressings and biocidal properties [9][10][11] . Its wellknown that copper is greatly toxic to microorganisms such as bacteria (Pseudomonas aeruginosa, Staphylococcus aureus, E.coli ,) to be considered an effective bactericidal can be used in water treatment and food packages 12 .…”

Development of nanotechnology, nanoparticles based product and its application is generating interest of many researchers due to its promising biological achievement. However, it is well known that inorganic nanomaterials are good antimicrobial agents. Among the various nanoparticles, metal nanoparticles as copper assume special importance due to its low cost and easy availability. In this study, the green synthesis method as eco-friendly approach is used to produce biologically copper oxide nanoparticles from Ficus carica leaf extract, stable CuO NPs were formed. The synthesized nanoparticles is characterized through the UV-Vis Spectrophotometer as it found to be 437 nm, Transmission Electron microscopy (TEM) investigated particle sizes in the range 51-62 nm and typical XRD patterns of the formed CuO NPs with high phase purity were obtained. Chitosan stabilizer as naturally occurring polymers was added to the prepared copper nanoparticles in different amounts to obtain Chitosan-CuO with different CuO percentage for longterm stability, for prevention the agglomeration of nanoparticles and enhancing their antibacterial efficacy. FTIR spectroscopy analysis was performed to copperoxide nanoparticle, chitosan, copperoxide chitosan composite to confirm that CuO nanoparticle was mixed with polymer. The antibacterial efficacy of chitosan, copper nanoparticles alone was studied against 22 bacterial pathogen like Coaggulase +ve S. aureus, methicillin-resistant Coaggulase -ve S. aureus, Klebsiella pneumonia as gram positive bacteria, Escherichia coli, e.coli o157 Salmonella typhi, Pseudomonas aeruginosa as gram negative bacteria that showed antibacterial activity against Gram positive as well as Gram negative bacteria. Antimicrobial activities of polymer/metal composites (Co oxide-chitosan nanoparticle) is studied against the same bacterial pathogen. The effect of the prepared Chitosan-CuO composite on ultrastructure of bacterial cells were evaluated by scanning electron microscopy (SEM), it was found that the antibacterial activity of Cu-chitosan nanoparticle composite is more greater than antibacterial activity of copper nanoparticles and chitosan alone that indicate the addition of chitosan stabilizer enhance at great extent the antimicrobial activity of CuO NPs.

“…The research was conducted for 5 nm particles and for 50 and 100 ppm concentrations. A characteristic "halo" around the bacterial colonies was observed, which indicated the growth inhibition (Jadhav et al 2011, Ramyadevi et al 2012. CuO-NPs (particle size: 22.4-94.8 nm) caused growth inhibition of S. aureus at the 100 ppm concentration, whereas the 5,000 ppm concentration inhibited the growth of P. aeruginosa and Proteus (Ren et al 2009).…”

Abstract:The aim of this paper is to present characteristics, toxicity and environmental behavior of nanoparticles (NPs) (silver, copper, gold, zinc oxide, titanium dioxide, iron oxide) that most frequently occur in consumer products. In addition, NPs are addressed as the new aquatic environmental pollutant of the 21 st century. NPs are adsorbed onto particles in the aquatic systems (clay minerals, fulvic and humic acids), or they can adsorb environmental pollutants (heavy metal ions, organic compounds). Nanosilver (nAg) is released from consumer products into the aquatic environment. It can threaten aquatic organisms with high toxicity. Interestingly, copper nanoparticles (Cu-NPs) demonstrate higher toxicity to bacteria and aquatic microorganisms than those of nanosilver nAg. Their small size and reactivity can cause penetration into the tissues and interfere with the metabolic systems of living organisms and bacterial biogeochemical cycles. The behavior of NPs is not fully recognized. Nevertheless, it is known that NPs can agglomerate, bind with ions (chlorides, sulphates, phosphates) or organic compounds. They can also be bound or immobilized by slurry. The NPs behavior depends on process conditions, i.e. pH, ionic strength, temperature and presence of other chemical compounds. It is unknown how NPs behave in the aquatic environment. Therefore, the research on this problem should be carried out under different process conditions. As for the toxicity, it is important to understand where the differences in the research results come from. As NPs have an impact on not only aquatic organisms but also human health and life, it is necessary to recognize their toxic doses and know standards/regulations that determine the permissible concentrations of NPs in the environment.Unauthenticated Download Date | 5/12/18 7:36 AM

Se utilizaron las cepas de Staphylococcus aureus ATCC 6538 (Gram positiva) y Escherichia coli ATCC 35218 (Gram negativa) para determinar el efecto inhibitorio mediante la concentración mínima inhibitoria de las nanopartícu-las diluidas en caldo de cultivo nutritivo y distribuidas en placas de ELISA. Las muestras de cobre cementado (obtenidas por procesos hidrometalúrgicos) y de cobre comercial fueron nanoestructuradas empleando un equipo de molienda mecánica. Los resultados indican que las nanopartículas de cobre comercial (a 2.5 horas de molienda) muestran acción inhibitoria del crecimiento de la cepa S. aureus y no así en la cepa E. coli. Asimismo, se determinó que la concentración mínima inhibitoria de la muestra de cobre comercial fue de 20 μg/mL frente a S. aureus. El cobre cementado (en su forma sólida y nanoestructurada) no mostró efecto inhibitorio del crecimiento en ninguna de las dos cepas estudiadas.Palabras claves: Actividad inhibitoria del crecimiento; bacterias Gram positivas; bacterias Gram negativas; nanopartículas de cobre; molienda mecánica.
