Fourier-transform infrared spectroscopy (FTIR) spectrum and the detected peaks of the surface of biosynthesized silver nanoparticles (AgNPs) from the cell-free filtrates of Talaromyces pinophilus (blue, a), Aspergillus fructus (red, b), Purpureocillium lilacinum (purple, c), Penicillium toxicarium (green, d), and Emericellopsis maritima (orange, e) grown in distilled water medium. Different peaks in the graph may indicate the presence of different functional groups.
