UV-Vis spectra of SeNPs. Fig. Inset shows PDA plates and PD broth flasks with (left-handed) and without sodium selenite (right-handed). NPs were separated from the culture broth, purified, dissolved in methanol and treated ultrasonically then the absorption was recorded in the range 200–800 nm. A UV-Vis spectrum of SeNPs synthesized by A. quadrilineatus, B UV-Vis spectrum of SeNPs synthesized by A. ochraceus, C UV-Vis spectrum of SeNPs synthesized by A. terreus, and D UV-Vis spectrum of SeNPs synthesized by F. equiseti
