Abstract

Due to optical properties, cadmium sulfide nanoparticles (CdSNP) are of interest for applications in several fields. The biosynthesis of this type of nanomaterials using the fungal biomass is a promising alternative because of the extracellular production of nanoparticles; however, the presence of cadmium could represent a challenge for microorganisms due to its well-known toxicity. Then, the present study was isolate fungi from environmental samples. Samples were obtained from polluted sites in different locations in Hidalgo State, Mexico. Firstly, fungi were isolated in culture media added with different cadmium concentrations to afterwards evaluate their ability to produce CdSNP. The synthesis was done using cadmium nitrate and elemental sulphur as raw materials using the fungal biomass of each isolate. Dynamic light scattering jointly with fluorescence and UV-Vis analysis were used to evidence the synthesis of CdSNP, which allowed to demonstrate the presence of nanoparticles with sizes below 100 nm, as well as absorption and emission bands characteristic of CdSNP at 310 and 515 nm, respectively. Thus, this study reports the ability of four cadmium-tolerant fungi to produce CdSNP.
