Biosynthesis of silver nanoparticles by Leishmania tropica
Biosynthesis and characterizations of nanoparticles have become an important branch of nanotechnology. A novel biosynthesis route for Silver Nanoparticles (Ag-NPs) was attempted in the present study using Leishmania tropica the causative agent of cutaneous leishmaniasis in different countries, particularly in Mediterranean region in Iraq. Silver nanoparticles were successfully synthesized from AgNO3 by reduction of aqueous Ag+ ions with the cell of L. tropica. AgNPs were irregular spherical in shape and the average particle size was about 35±5 nm characterized by means of UV–vis absorption spectroscopy and scanninng electron microscopy (SEM) images. The efficiency of L. tropica for synthesis of silver nanoparticles was found to be higher; also this method was cost effective and easily scaled up for large scale synthesis.
