Biosynthesis of Cadmium Sulfide Nanoparticles by the Fungi Fusarium sp.

ABSTRACT CdS nanoparticles have attracted attention due to its optical and electrical properties. Conventional methods provide some problems, such as particle size, high-pressure requirements, and the use of toxic materials, for its synthesis. It is well known that many microorganisms can provide inorganic materials either intra- as extracellularly. In this work, the authors present the results of the CdS nanoparticles synthesis using Fusarium sp. biomass as a sustainable synthesis procedure, after its exposition with a CdSO4 solution. Nanoparticles were characterized by ultraviolet-visible, x-ray diffraction, and atomic force microscopy.
