“…The synthesis method depends on the high reactivity of the copper complex as well as on its concentration and agitation speed during the reaction. These factors are very specific for controlling the morphology, particle size and distribution (Betancourt-Galindo et al 2014). The variation in the particle sizes, such as 22, 33, and 56 nm, was attributed to the different times at which they are formed (Gopinath et al 2012).…”

Pseudomonas aeruginosa, an opportunistic pathogen frequently associated with nosocomial infections, is emerging as a serious threat due to its resistance to broad spectrum antimicrobials. The biofilm mode of growth confers resistance to antibiotics and novel anti-biofilm agents are urgently needed. Nanoparticle based treatments and therapies have been of recent interest because of their versatile applications. This study investigates the anti-biofilm activity of copper nanoparticles (CuNPs) synthesized by the one pot method against P. aeruginosa. Standard physical techniques including UV-visible and Fourier transform infrared spectroscopy, X-ray diffraction and transmission electron microscopy were used to characterize the synthesized CuNPs. CuNP treatments at 100 ng ml(-1) resulted in a 94, 89 and 92% reduction in biofilm, cell surface hydrophobicity and exopolysaccharides respectively, without bactericidal activity. Evidence of biofilm inhibition was also seen with light and confocal microscope analysis. This study highlights the anti-biofilm potential of CuNPs, which could be utilized as coating agents on surgical devices and medical implants to manage biofilm associated infections.

In nanotechnology, using of metallic nanoparticles (MNPs) has obtained major attention for over a century because of their unique properties in nano scale. In this paper, the effect of three factors (incubation time, concentrations of copper sulfate and glucose) on the biosynthesis of copper (II) oxide nanoparticles (CuO NPs) by Halomonas elongata IBRC-M 10214 and the antibacterial activity of nanoparticles were evaluated. Experiment design and analysis of Taguchi method were carried out by Qualitek-4 software. Effect of CuSO4 concentration (1.4, 2.8 and 5.6 mM), incubation time (48, 72 and 96 h) as three different levels was measured as three major factors in the biosynthesis of metallic nanoparticles. Synthesized CuO nanoparticles were characterized by utilizing ultraviolet-visible (UVVis) spectroscopy, X-ray diffraction (XRD), Fourier transform infra-red (FT-IR) spectroscopy and field emission scanning electron microscope (FESEM) techniques. Among the three factors, results illustrated that considerable effect was related to CuSO 4 concentration. These analyses demonstrated that the average CuO nanoparticles crystalline size was 57-79 nm with rectangular shape. Also, for evaluating of antibacterial effects, maximum zone of inhibition, two important multidrug resistant pathogenesis bacteria, Escherichia coli ATCC 25922, and Staphylococcus aureus ATCC 43300 were used. Antibacterial assay of CuO nanoparticles showed antibacterial activity toward the pathogenic bacterial strains of E. coli by 5 mm and S. aureus by 5.5 mm for maximum zone of inhibition. In conclusion, this study presented simple, low expensive, eco-friendly and high productivity in the fabrication of CuO nanoparticles. In addition, these metallic nanoparticles had antibacterial effect that could be usable in medicinal aspect for fighting against prominent pathogen bacteria such as E. coli ATCC 25922 and S. aureus ATCC 43300.

“…The same technique has also been used for the preparation of CuNPs (Capek 2004). Controlled current electrolysis using surfactants, thermal reduction, sono-chemical reduction, aquous phase synthesis by using organic nanoparticles, liquid phase plasma reduction method, one-pot synthesis, thermal decomposition and controlled chemical reduction were other methods reported so far (Betancourt-Galindo et al 2014;Dhas et al 1998;Huang et al 2006;Lee et al 2014;Pileni 1997;Saldanha et al 2014;Singh et al 2014;Yang et al 2003).…”

We report an eco-friendly method for the synthesis of copper nanoparticles (CuNPs) using Citron juice (Citrus medica Linn.), which is nontoxic and cheap. The biogenic copper nanoparticles were characterized by UV-Vis spectrophotometer showing a typical resonance (SPR) at about 631 nm which is specific for CuNPs. Nanoparticles tracking analysis by NanoSight-LM20 showed the particles in the range of 10-60 nm with the concentration of 2.18 × 10(8) particles per ml. X-ray diffraction revealed the FCC nature of nanoparticles with an average size of 20 nm. The antimicrobial activity of CuNPs was determined by Kirby-Bauer disk diffusion method against some selected species of bacteria and plant pathogenic fungi. It was reported that the synthesized CuNPs demonstrated a significant inhibitory activity against Escherichia coli followed by Klebsiella pneumoniae, Pseudomonas aeruginosa, Propionibacterium acnes and Salmonella typhi. Among the plant pathogenic fungi tested, Fusarium culmorum was found to be most sensitive followed by F. oxysporum and F. graminearum. The novelty of this work is that for the first time citron juice was used for the synthesis of CuNPs.
