MICROBIAL FABRICATION OF METALLIC NANOPARTICLES: STRUCTURAL CHARACTERIZATION AND INDUSTRIAL APPLICATIONS

Kdy: 14. března 2019 od 10h
Kde: Přednášková místnost - 4. patro CxI TUL.
Lektoři: Prof. Mohamed L. Merroun z Univerzity v Granadě, Oddělení mikrobiologie, Španělsko

Microorganisms, widely distributed in nature, interact efficiently with metals through different mechanisms including biosorption, intracellular accumulation, biomineralisation, oxidation/reduction, and chelation. These metal microbial interactions processes, affect the behaviour and fate of these inorganic contaminants, and presented different industrial applications. For instance, using different electron donors, microbes are able to reduce precious ionic metals (Pd, Pt, Au, Ru, Se) producing monometallic/bimetallic nanoparticles (NPs) with different size, shape and atomic structures. These biogenic nanostructures could be used as catalysts for different chemical reactions (Pd, Ru, Pt, Au NPs), as antimicrobial activity (antibiotic alternatives against infectious diseases, SeNPs, AgNPs, etc.), in electronic industries, etc
