Abstract :

The paper reports a low cost biological method for synthesis of Zinc oxide nanoparticles (ZnO NP). The method involves probiotic microorganism ( Lactobacillus plantarum ) mediated chemical transformation leading to formation of nanosized materials. The structural and optical characterizations of the obtained ZnO NP was carried out using X-Ray diffraction (XRD), Scanning electron microscopy (SEM) and UV-Visible spectroscopy. The results confirmed the obtained material to be ZnO having size in the range 45 to 80 nm. The studies on electrical and optical properties of the ZnO nano particles are reported in this paper.
