The biosynthesized selenium nanoparticles were characterized by using UV Spectroscopy, dynamic light scattering, transmission electron microscopy (TEM), X-ray diffraction (XRD) spectroscopy and scanning electron microscopy with energy dispersive X-ray (SEM-EDX). The size of biosynthesized selenium nanoparticles obtained by TEM was in the range of 20-80nm. There were some large particles of more than 100nm but less than 150nm also seen. XRD spectroscopy analyses revealed that biosynthesized selenium nanoparticles were hexagonal crystalline in nature. The FTIR spectroscopy study confirms presence of functional groups which were associated with proteins and biomolecules excreted extracellularly by fungi. These proteins and biomolecules believe to serve as template for reduction and stabilization of selenium nanoparticles. Moreover, these biomolecules were may also help in controlling size and aggregation.
