“…Cu is not stable at the nanometre scale and oxidises fairly rapidly to form copper oxide (CuO) [37]. Therefore, if Cu nanoparticles are to be used in an application after their synthesis, they need to be stabilised.…”

Over the past few decades interest in metallic nanoparticles and their synthesis has greatly increased. This has resulted in the development of numerous ways of producing metallic nanoparticles using chemical and physical methods. However, drawbacks such as the involvement of toxic chemicals and the high-energy requirements of production make it difficult for them to be widely implemented. An alternative way of synthesising metallic nanoparticles is by using living organisms such as bacteria, fungi and plants. This "green" method of biological nanoparticle production is a promising approach that allows synthesis in aqueous conditions, with low energy requirements and low-costs. This review gives an overview of some of these environmentally friendly methods of biological metallic nanoparticle synthesis. It also highlights the potential importance of these methods in assessing nanoparticle risk to both health and the environment.techniques, which are generally low-cost and high-volume. However, the need for toxic solvents and the contamination from chemicals used in nanoparticle production limit their potential use in biomedical applications [15]. Therefore a "green", non-toxic way of synthesising metallic nanoparticles is needed in order to allow them to be used in a wider range of industries. This could potentially be achieved by using biological methods.Many bacteria, fungi and plants have shown the ability to synthesise metallic nanoparticles and all have their own advantages and disadvantages (Table 1) [16][17][18]. Intracellular or extracellular synthesis, growth temperature, synthesis time, ease of extraction and percentage synthesised versus percentage removed from sample ratio, all play an important role in biological nanoparticle production. Finding the right biological method can depend upon a number of variables. Most importantly, the type of metal nanoparticle under investigation is of vital consideration, as in general organisms have developed resistance against a small number of metals, potentially limiting the choice of organism. However synthetic biology; a nascent field of science, is starting to address these issues in order to create more generalised chassis, able to synthesise more than one type of metallic nanoparticle using the same organism [19]."Natural" biogenic metallic nanoparticle synthesis can be split into two categories. The first is bioreduction, in which metal ions are chemically reduced into more stable forms biologically. Many organisms have the ability to utilise dissimilatory metal reduction, in which the reduction of a metal ion is coupled with the oxidation of an enzyme [20]. This results in stable and inert metallic nanoparticles that can then be safely removed from a contaminated sample. The second category is biosorption. This involves the binding of metal ions from Journal of Nanomedicine & Nanotechnology J o u rna l of N a n o m ed icine & N a n o te chnolo g y

“…Several methods have been developed to synthesize copper nanoparticles including electrochemical [7], chemical reduction [8], thermal decomposition [9], microemulsion [10], photochemistry [11], laser ablation [12], gas evaporation [13], and biological methods [14]. In general, the methods currently most widely used is the chemical method because the method is simple and capable of producing high-quality nanoparticles [15].…”

Copper nanoparticles are the most frequently used materials in the field of nanoscience because of their electrical, optical, biomedical, antifungal, and antibacterial properties. The synthesis of copper nanoparticles with biological methods is known to be environmentally friendly, inexpensive, simple, and capable of producing better nanoparticles than other methods. This study aims to determine the feasibility of an industrial project to manufacture Cu nanoparticles through a biosynthetic method using Citrus medica Linn. extract and evaluate it from an engineering and economic point of view. Some of the parameters used for economic evaluation are Payback Period (PBP), Break Even Point (BEP), and Cumulative Net Present Value (CNPV). The analysis is supported using data taken from online shopping websites. The results showed that the number of Cu nanoparticles that could be produced in one year was 24,000 kg. The total initial capital cost is 272,640.00 USD and the profit is 698,655.90 USD/year. PBP occurred in the 3rd year with the CNPV/TIC value reaching 3.746% in the 9th year. Based on the economic evaluation, the project is concluded to be feasible to run with the anticipated tax and percentage of sales. The results of this study are expected to provide an overview of the economic evaluation of industrial-scale Cu nanoparticles production by biosynthetic method using Citrus medica Linn. extract.

“…Between all nanoparticles, copper nanoparticles, because of their various precursors and especially because of very different applications, such as electrical, catalytical and optical, are so important [31] [32]. There are different methods for copper nanoparticles fabrication [33]- [41]. But mechanical methods are the methods that are more common for copper nanoparticles fabrication and thermal decomposition is the most economical and easy way [42] [43] [44].…”

“…But mechanical methods are the methods that are more common for copper nanoparticles fabrication and thermal decomposition is the most economical and easy way [42] [43] [44]. Bis-(acetylacetonato)-copper (II) was selected as a precursor, because its behavior is very same to bis-oxalate copper (II) which has been applied before and is decomposed at enough low temperature (about 200˚C) to prevent very probable precipitation of the produced metallic particles, and its decomposition gives water and carbon compounds, which does not lead to real human health problems [33] [42]. It was investigated the effect of surfactants structural role in the yield and grain size of nanoparticles too.…”

Between all precursors of copper complex, bis-(acetylacetonato)-copper (II) and bis-oxalate copper (II) with very close structures are two of the best representatives for copper nanoparticles synthesis. In this research, only bis-(acetylacetonato)-copper (II) in presence of some effective non-ionic surfactants such as Triton X-100, Dodecylamine, Tween 80 and also triphenylphosphine as a reducing agent via thermal decomposition process was used for copper nanopaticles synthesis. Two shif-base E19 and E22 complexes were also used for the investigation of these kinds of shif-base complexes capabilities by this method as precursors and all results were compared with each other. Between all surfactants, Triton X-100 gave the best yield with the largest grains. The techniques used for characterization of copper nanoparticles were TEM, EDX, FT-IR and XRD. TG-DTA and CV were used for characterization of bis-(acetylacetonato)-copper (II) complex.
