Abstract


Introduction

Biosynthesis of tellurium nano particles (tnps) has great advantage since it has no chemical contamination in the environment. these nano particles have pharmaceutical, medical, industrial and environmental implications. in the renewable energy appliances as solar cells, tellurium and selenium are the main building blocks. it is believed that in the human body, tellurium (iv) compounds have important roles in thiol redox biological activity and ammonium trichloro tellurate may be a future drug for the treatment of parkinson’s disease. the goal of this study was to biosynthesize tnps with the least harm to the environment.

Methods

Tnps produced in a green method using culture biomass of streptomyces isolate b2.1369f isolated from soils of sarcheshmeh copper complex, kerman, iran to reduce 0.002 m potassium tellurite. tem, sem, dls, and uv-visible spectroscopy used to characterize biosynthesized tnps. all experiments performed as triplicates to ensure persistency.

Results

Biosynthesized tnps had dark black color, their uv-visible spectroscopy spectrum indicated no prominent peak, electron micrographs of tem, sem indicated amorphous particles and dls results showed average particle size of 48.8 nm.

Conclusion

Use of this technique is a green procedure to produce tnps. for future, quantitative analysis is needed to attain efficacy of procedure, optimize purification and exclude impurities.
