In this study, we describe a green and simple procedure for biosynthesis of ZnO nanoparticles using Candida albicans as eco-friendly reducing and capping agent. The synthesized ZnO nanoparticles were characterized by UV-vis spectroscopy, powder X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL), thermo gravimetric analysis (TGA) and differential thermal analysis (DTA). The prepared nano-particles were used as catalyst for the

The target molecules were obtained in good to excellent yields applying the current method. ª 2013 Production and hosting by Elsevier B.V. on behalf of King Saud University.
