Synthesis and Stabilization of Cobalt and Cooper Nanoparticles by Chitosan Bombyx mori

The cobalt and copper nanoparticles were prepared by reduction of metals using the 2-propanol at presence of chitosan Bombyx mori. The structural measurements show that the chitosan molecules prevent the agglomeration and oxidation of metal particles. It was established that chitosan is a nano-reactor and its concentration influences on the size and distribution of NP in a polymeric matrix.
