Chemical Synthesis of Copper Nanoparticles

Abstract

ABSRTACTMetal nanoparticles have attracted considerable interest particularly because of the size dependence of physical and chemical properties and its enormous technological potential. Among different metal nanoparticles, copper nanoparticles have attracted great attention because copper is one of the most key metals in new technology. Chemical methods are used to synthesize copper nanoparticles and among them chemical reduction is the most frequently applied method for the preparation of stable, colloidal dispersions in organic solvents. In this paper, a brief overview of the current research worldwide in the chemical synthesis of copper nanoparticles is discussed.

Copper: Synthesis Techniques in Nanoscale and Powerful Application as an Antimicrobial Agent

“…leaves is a successful option to obtain stable spherical Cu NPs about 15-20 nm [37]. Microemulsion reduction method (Figure 2(a)) or colloidal synthesis involves the use of immiscible water-oil, oil-water, and water supercritical carbon dioxide forming surface-active microarrays [38]. Sonochemical reduction is based on ultrasonic waves (Figure 2(b)) with a frequency about 20 kHz to 10 MHz; the reaction is active by a physical phenomenon of acoustic cavitation [39].…”

“…The investigations are new trends to developing a system to obtain NPs that offer the least possible harm to the environment and which are inexpensive, but the road is still long and uncertain, although efforts are increasingly higher. As estimated for 2020, the production of nanoparticles focused on nanomaterials will be 20 times higher than that in the last 10 years [38].…”

“…Microemulsion is the most common method for the copper NPs synthesis involving the use of tensioactive substances and organic solvents and a lot of energy and high costs [16,17]. These are the main reasons that it seeks to develop new methods friendly with the environment [84] by incorporating low toxicity substances such as alginate used as stabilizing agent [38] or chitosansilver-copper organometallic to form 33 bimetallic particles. The investigations are new trends to developing a system to obtain NPs that offer the least possible harm to the environment and which are inexpensive, but the road is still long and uncertain, although efforts are increasingly higher.…”

Ranolazine-Functionalized Copper Nanoparticles as a Colorimetric Sensor for Trace Level Detection of As3+

“…As an alternative solution to the above-mentioned problems, metal nanoparticles (NPs) have witnessed tremendous growth due to their impressive optical, physical, and electrical qualities in modern ages, resulting in the mitigation of several complicated problems. Compared with costly silver, gold, and platinum NPs, the cost of forming copper nanoparticles (Cu NPs) is certainly lower [15]. However, the novel optoelectronic features associated with copper and silver as well as gold nanoparticles facilitate the use of these in various applications, such as sensors, catalysis, electronics, biomedicine, and bioanalytics [16].…”

Fine Ultrasmall Copper Nanoparticle (UCuNPs) Synthesis by Using Terminalia bellirica Fruit Extract and Its Antimicrobial Activity

“…Copper nanoparticles are having wide variety of useful properties like good thermal and electrical conductivity, which might be used in electronics or optical properties, which might be exploited in catalytic, diagnostic, sensoring, and therapeutic applications [5][6][7][8], which is available at much lower cost than precious noble-metal nanoparticles. There are so many methods are developed for the synthesis of copper nanoparticles such as chemical reduction [9], thermal reduction [10], wet chemical route [11], micro emulsion techniques [12], laser ablation [13], polyol method [14], DC arc discharge method [15] and bio synthesis [16]. Among these methods green synthesis method requires low temperature, less cost, nontoxic and ecofriendly.…”
