Plant Extract-Assisted Green Synthesis and Characterization of Copper Nanocomposite

The era of nanomaterials is here. Science has undergone a revolution thanks to nanotechnology. The use of nanoparticles has greatly helped every area of technology. Nanomaterials were created through different chemical and physical methods. But green synthesis has received a lot of attention recently, especially when it involves the usage of extracts of plants or microbes. The promotion of environmental sustainability can benefit from this. Because green synthesis is simpler, cheaper, and more reproducible than other methods, it is also a more advanced way to make nanomaterials. Compared to other methods, plants create more stable metal nanocomposites and/or nanoparticles, and scaling up is easy. Additionally, there is less chance of contamination. The most prevalent element among the numerous metals is copper, which is essential to an organism's ability to operate normally. When compared to modern antibiotics, copper nanoparticles and/or nanocomposites show stronger antibacterial activity. Due to a lack of compiled study about copper-based green synthesis, this article addressed an inclusive assembly of investigations concentrated mostly on the plant-based green synthesis of copper nanoparticles and/or nanocomposites. We also discuss the various advantages and disadvantages of copper nanocomposites and/or nanoparticles, in addition to the limitations and advantages of physical and chemical characterization techniques for copper nanocomposites. Lastly, the latent uses of green synthesized copper nanocomposites and nanoparticles, such as antimicrobial activity, catalysis, biosensing, drug delivery, and so forth have been reviewed and discussed.
