Background: The synthesis of metallic nanoparticles is a lively area of education and, more importantly, “application research” in nanotechnology. A wide range of chemical and physical procedures might be used for synthesis of metallic nanoparticles. However, these methods are swarming with many problems including use of toxic solvents, generation of hazardous by-products, and high energy consumption. Accordingly, there's a vital need to develop environmentally benign procedures for synthesis of metallic nanoparticles. A promising approach to realize this objective is to take advantage of the wide array of biological resources in nature. Indeed, over the past several years, plants, algae, fungi, bacteria, and viruses have been used for production of low-cost, energy-efficient, and nontoxic metallic nanoparticles.
 Aim: The aim of the current study was to synthesise and characterize the copper Nanoparticles mediated with red tea.
 Materials and Methods: ​The green synthesis of the copper Nanoparticles was done using red tea. Morphological characters like the shape and size of the obtained copper nanoparticles were done by transmission electron microscopy (TEM).
 Results: The results confirmed that the synthesised red tea mediated nanoparticles are eco-friendly, good and non toxic. TEM images showed that the copper nanoparticles were well dispersed, crystalline in nature. Copper nanoparticles are spherical in nature. The particles size was ranging from 40 to 90 nm, The TEM image shows that nanoparticles are not combined but are separated by equal interspace between the particles, which was confirmed by microscopy visualising under the higher resolution.
 Conclusion: ​In this study, a simple, biological and low-cost approach was done for the preparation of copper nanoparticles using red tea extract. Thus the green synthesized copper nanoparticles can be subjected to the various other biological activities to test their biological efficiency and can be a pioneering step towards the shift to eco friendly medicine.
