Green Biosynthesis of Silver Nanoparticles from Wild Mushroom (Ganoderma lucidum) First Time in Iraq

Nowadays there is an increasing interests about nanoparticle due to its application in medical and industrial products, green rout and safely producing of nanoparticles consider important for recent life technology, silver nanoparticles (AgNPs) one of the most safe compound to human and environment due to its low effect an low toxicity even with direct contacting and consuming release low particles of silver, for these reasons , the availability and low costing technology we produced silver nanoparticles from eco-friendly mushroom G. lucidum first time in Iraq. AgNPs were prepared by using aqueous extract of G. lucidium as a reducing agent for silver nitrate (AgNO3). The characteristics of silver- anoparticles were determined, including: Determining the highest absorption of silver nanoparticles by UV-VIS spectrophotometer, the shape and size of silver nanoparticles by atomic force microscopy (AFM), as well as determining the type of chemical bonds or functional groups bound to the prepared AgNPs by Fourier-transform infrared spectroscopy-FTIR. Scanning Electron Microscopy used for study of Particle size and shape. The results showed the emergence of a spectral imaging beam using a spectrophotometer that ranged between 350-900 nm, where the best absorption beam was at a wavelength of 450 nm, while the result of AFM showed the surface topography of silver nanoparticles with an average size of 62.78 nm. FTIR spectrum revealed strong absorption peaks 1091-3434 cm-1, as well as their role in the stability of these molecules. The size of spherical particles ranged between 17.15 - 25.81 nanometers under SEM.
