“…The authors propose initial formation of Cu 2 O and then the reduction to Cu(0) (confirmed by XRD analyses) that could be evidenced by a color change from blue-green to ocher yellow, and then red-violet. The largest particles were obtained with PEG20000, and the smallest with PS80 [48].…”

“…Chemical reduction of copper ions with sodium borohydride and stabilization by polyvinylpyrrolidone (PVP) using copper chloride as precursor giving 7 nm size of NP's by TEM and SEM analysis [29]. Copper nanoparticles of range 38 to 50 nm were prepared using solvothermal reduction method with glycerol (reducing agent) and various surfactants for stabilizing the particles [30]. The synthesis of NPs by thermal decomposition in liquid phase has achieved attention due to production of stable nanoparticle with easy method and also has shown antibacterial activity against E. coli [31], [32].…”

An emerging field of science “Nanotechnology” which is involved in manipulation of atoms and molecules has shown great potential in all fields of sciences. Nanotechnology deals with nanoparticles ranging from size 1 to 100 nm in diameter, due to small size and high surface area eventually increases the state of activity. This review focuses on metal and metal oxide nanoparticles and mainly on green synthesis, characterization and application of copper nanoparticles. Green synthesis of copper and copper oxide (Cu and CuO) is economically beneficial and ecofriendly. Copper nanoparticles are used in diverse fields such as biomedicine, pharmaceuticals, bioremediation, molecular biology, bioengineering, genetic engineering, dye degradation, catalysis, cosmetics and textiles. Structural properties and biological effects of copper nanoparticles have promising effectivity in field of life sciences.

“…The in situ process used to generate the micro/nano scale copper particles represents an eco-friendly coating method (Sedighi et al 2014;Dobrovolný et al 2015) that minimizes exposure of the user to potentially toxic nanoparticles (Raffi et al 2010). Micro/nano scale copper particles in the heat treated wood adhere to and disrupt the cytoderm of mildew through a series of electrostatic interactions with the cell wall that serve to inhibit fungal growth (Mondal and Mani 2012;Civardi et al 2015).…”

The dimensional stability and resistance to degradation of wood can be improved using high temperature heat treatment under anaerobic conditions; however, mildew growth can have a deleterious impact on its appearance and commercial value. In this study, wood samples were impregnated in copper-containing solutions at high pressure before being recovered and cured at high temperatures to create treated wood samples with nano copper particles. This copper impregnated wood (up to 6.35% copper content) suppressed the growth of Botryodiplodia theobromae Pat. and Aspergillus niger van Tieghem with 100% efficiency, and Penicillium citrinum Thom with 75% efficiency. However, the growth of Trichoderma viride Pers. was not suppressed. These results demonstrate that copper curing can be used to extend the scope, performance, and lifetime of heat-treated wood, enabling it to be used for a new range of applications.
