“…Significant DNA damage was detected only when Cu was injected as CuSO4 in comparison to controls. These data suggest that Cu nanoparticles are less toxic than at their macroscale size (Isani et al, 2013). Another report noted that copper toxicity to A6 cells of a frog (Xenopus laevis) depends on the form of copper and the state of the cell, so that the effects were produced before stages of differentiation and proliferation.…”

ABSTRACT:Copper was registered as the first solid antimicrobial material. Its availability makes it an important option as an antibacterial agent. At nanoparticle size it does not exceed 100 nm, allowing close interaction with microbial membranes, enhancing its effect even more. Copper generates toxic hydroxyl radicals that damage cell membranes of Gram-negative and Gram-positive bacteria, among the latter, Enterococcus faecalis, which are present in infected radicular canals. Synthesis of metal nanoparticles with antimicrobial properties has become a viable alternative and has promising applications in the fight against pathogenic microorganisms. Furthermore, the use of some polymers to stabilize nanoparticles increases their release time and may as well decrease the risk of bacterial recolonization and biofilm formation within the ducts, enhancing the antimicrobial properties of these compounds.The aim of this article is to conduct a systematic review of the literature on antimicrobial copper nanoparticles, their current applications and their potential use in the area of oral health, specifically in the field of endodontics.

“…However, Zhao et al (2007) showed that particle size is directly correlated with relevant factors that affect nanotoxicity in organisms. The characteristics of waterborne metal NP have been reported in several studies by using the single particle sized surface area, aggregation, and zeta potential (Zhao et al, 2011;Shaw et al, 2012;Isani et al, 2013). However, each study has inherent limitations about how the different NP sizes can induce a variety of particle properties that subsequently affect nanotoxicity.…”

“…To date, the studies regarding the physiological effects of nano-sized waterborne CuNP on fish included 26.7 nm-zebrafish (Danio rerio), 20-40 nm-carp (Cyprinus carpio), and 87-and 164 nm-rainbow trout (Oncorhynchus mykiss) systems (Griffitt et al, 2008(Griffitt et al, , 2009Zhao et al, 2011;Shaw et al, 2012;Al-Bairuty et al, 2013;Isani et al, 2013). Dose-response effects of sizedependent metal NPs were also found in in vitro osteoblastic MC3T3-E1 cells and PC12 pheochromocytoma cell studies, indicating that the smaller metal NPs remained more toxic than larger ones on cell toxicity (Carlson et al, 2008;Kim et al, 2012;Prasad et al, 2013).…”

Toxicokinetic Modeling Challenges for Aquatic Nanotoxicology

Nanotoxicity has become of increasing concern since the rapid development of metal nanoparticles (NPs). Aquatic nanotoxicity depends on crucial qualitative and quantitative properties of nanomaterials that induce adverse effects on subcellular, tissue, and, organ level. The dose-response effects of size-dependent metal NPs, however, are not well investigated in aquatic organisms. In order to determine the uptake and elimination rate constants for metal NPs in the metabolically active/detoxified pool of tissues, a one-compartmental toxicokinetic model can be applied when subcellular partitioning of metal NPs data would be available. The present review is an attempt to describe the nano-characteristics of toxicokinetics and subcellular partitioning on aquatic organisms with the help of the mechanistic modeling for NP size-dependent physiochemical properties and parameters. Physiologically-based pharmacokinetic (PBPK) models can provide an effective tool to estimate the time course of NP accumulation in target organs and is useful in quantitative risk assessments. NP accumulation in fish should take into account different effects of different NP sizes to better understand tissue accumulative capacities and dynamics. The size-dependent NP partition coefficient is a crucial parameter that influences tissue accumulation levels in PBPK modeling. Further research is needed to construct the effective systems-level oriented toxicokinetic model that can provide a useful tool to develop quantitatively the robustly approximate relations that convey a better insight into the impacts of environmental metal NPs on subcellular and tissue/organ responses in aquatic organisms.

Carbon foams (CFms) exhibit excellent physical properties, including good thermal conductivity, low density, high porosity and specific surface area, good vibration damping and shock absorption properties, and low thermal expansion coefficients. These properties are attractive in various applications such as thermal and electrical transfer devices, electrochemical supercapacitors, catalyst supports, gas adsorbents, filtration systems, and electromagnetic shielding. However, compared to metals and polymers, CFms do not exhibit good mechanical or thermal properties because of their porous structure; these shortcomings have limited the application of CFms in various fields [1][2][3][4].Researchers have sought to improve the mechanical and thermal properties of CFms through the addition of carbon nanofibers, carbon nanotubes, graphite and metal plating [5,6]. CFms/copper composites were recently studied by Johnson et al. [7], who examined the thermal conductivity of wood-derived graphite and copper-graphite composites produced via electrodeposition. The thermal conductivity of the biomorphic graphite/copper composite was 10 times greater than that of biomorphic graphite, with the graphite/copper composites exhibiting a thermal conductivity ranging from 20 to 21 W/mK [7]. Zhai et al. [8] studied the effects of vacuum and ultrasonic co-assisted electroless copper plating on CFms and noted increased conductivity ranging from 700 to 1885.8 S/cm, and increased compressive strength ranging from 0.70 to 1.66 MPa with increasing copper content.Cu exhibits high thermal and electrical conductivities, in the range of 350-400 W/mK and 59.17-59.59 × 10 6 Ω -1 m -1 , respectively; and it can be adhesively bonded with carbon matrices such as carbon nanofoams, mesoporous carbon templates and nanotube/nanofiber assemblies through electrodeposition, electroless deposition, coating, and doping. Numerous researchers have reported that, when used as battery electrodes, metal-bonded carbon matrices exhibit high electrical capacity and increased oxidative stability compared to nontreated graphite foams [5,[9][10][11][12][13][14][15]. However, preparing CFms with copper presents various problems. The coating of metal to the inner surfaces of porous materials that have small and deep pores using electrodeposition, metal layer joining, and electroless plating methods is difficult. Methods such as vacuum and ultrasonic mechanical processes are needed in addition, to uniformly coat metals onto the inner surfaces of CFms [16][17][18][19][20]. Alternatively, CFms have been uniformly embedded with copper via CuSO 4 solutions without the use of any mechanical process [21].In this study, we investigate economical and convenient methods of preparing coppernanoparticle-embedded CFms (Cu-CFms) using CuSO 4 solutions with different concentrations. The thermal and mechanical properties of the resulting Cu-CFms were investigated along with changes in the density and nanoparticulate size of the Cu.Isotropic pitch (IP) (pyrolyzed fuel oil; GS Caltex, Seoul...
