Biosynthesis of copper nanoparticles from plant extract and bacteria - a review
by Ravindra Ashok Sharma
International Journal of Nanoparticles (IJNP), Vol. 13, No. 3, 2021

Abstract: Copper and its salt have been used for a long time as it is non-toxic, cheaper, antibacterial/antifungal agent, and has high potential in a wide range of catalytic, biological, and sensor application. There has been a great development of various methods for the synthesis of copper nanoparticles, but there have been several limitations in copper nanoparticle synthesis by chemical and physical methods. Thus the interest has been shifted towards the green synthesis of copper nanoparticles which is cheaper, easy, quick, and environment friendly. As there are very few reviews available on the biosynthesis of copper nanoparticles of which most reviews are focused on either application or biosynthesis, not both. Thus, this review provides an overview of recent studies on green synthesis of copper nanoparticles by using plants, bacteria, fungi, and the advantages of using plants over bacteria and fungi for copper nanoparticle synthesis. This review also focuses on the characterisation methods of copper nanoparticles and some applications of copper nanoparticles. From this review, it can be concluded that further research on improving the large-scale production and downstream processing technique needs to be done.
