Iodine-stabilized Cu nanoparticle chitosan composite for antibacterial applications.

We report herein the synthesis of a new composite consisting of Cu nanoparticles (NPs) and chitosan (CS), which has been found to be stable in the presence of molecular iodine and has also high antimicrobial activities. The composite could be obtained when aqueous CuSO(4) was treated with hydrazine in the presence of CS. The spherical Cu NPs present in the… CONTINUE READING
