Application of biotechnological methods for the biosynthesis of metal nanoparticles

Polimery 2011, No 2, 140


DOI: dx.doi.org/10.14314/polimery.2011.140

Summary

Studies on the possibilities of the application of cosmopolitan moulds of the Penicillin group type for the extracellular synthesis of silver nanostructures have been presented. A number of moulds were isolated from their natural habitat and studied. The influence of reaction conditions such as the age of the cell culture and concentration of biomass on the structure, dimensions and stability of the obtained nanoparticles as well as on this biosynthesis process as a whole was evaluated. The formation of the nanoparticles was monitored visually (Fig. 1) and with UV-Vis spectroscopy (Figs. 2—10).


Key words: silver nanoparticles, biosynthesis, moulds, Penicillium
