A novel method to prepare copper microspheres via chemical reduction route

Copper, due to its high electrical conductivity, catalytic, and antimicrobial activity, is widely used in various applications. Also, the abundance of copper and its low cost make it a suitable alternative to Ag or Au for commercial application. Monodispersed spherical copper particles with average...
