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. Various methods for the synthesis of copper nanoparticles employing chemical, physical and
biological techniques considering bottom-up and top-down methods synthesis have been studied.
Nanoparticles, especially copper nanoparticles (CuNPs), have gained significant attention in recent
years due to their unique physical, chemical, and biological properties, leading to a wide range of
applications in various fields. This paper provides a comprehensive overview of different synthesis
methods employed for the fabrication of copper nanoparticles and highlights their diverse applications.
The synthesis methods discussed include chemical reduction, physical methods, green synthesis, and
biological approaches. Chemical reduction methods involve the reduction of copper ions using various
reducing agents, resulting in controlled size and shape of nanoparticles. Physical methods encompass
techniques such as laser ablation, ball milling, and sputtering, providing distinct advantages in terms of
size control and purity. Green synthesis, utilizing plant extracts, microorganisms, or other eco-friendly
sources, has gained popularity for its sustainability, and reduced environmental impact. The paper
explores the influence of synthesis parameters on the size, shape, and stability of copper nanoparticles,
emphasizing the importance of tailoring these properties for specific applications.
