Abstract

NPs are tiny materials having size ranges from 1 to100 nm. They can be classified into different classes based on their properties, shapes or sizes. Over recent decades, Tellurium applications continued to emerge in different fields including metallurgy, glass industry, electronics, and applied chemical industries. Te nanostructures are used in labeling, imaging, and targeted drug delivery systems and are tested for antibacterial or antifungal properties. In this paper, the green synthesis of Te nanoparticles by the marine bacterial strain MTe05is described. Te nanoparticles display an optical absorption bond at 400 nm and the presence of elemental tellurium was confirmed by Energy dispersive x ray (EDX) analysis. This strain synthesized nanoparticles under a variety of conditions. Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) micrographs showed both extra and intra cellular synthesis of Te nanoparticles.
