Název v původním jazyce

The composites of graphene oxide with metal or semimetal nanoparticles and their effect on pathogenic microorganisms

Popis výsledku v původním jazyce

Herein we describe a synthesis and testing of composites based on graphene oxide as a carrier in composites with metal or metalloid based nanoparticles (Cu, Zn, Mn, Ag, AgP, Se) as an antimicrobial agent for bacterial strains (Staphylococcus aureus (S. aureus), methicillin-resistant S. aureus (MRSA) and Escherichia coli (E. coli)). The composites were firstly applied in the identical 300 pM concentrations on all types of model organisms and their effect was observed spectrophotometrically by decrease inabsorbance values in comparison with the control untreated strain. The most pronounced inhibition of S. aureus growth was observed after application of graphene oxide composite with selenium nanopar-ticles (87.4% decreases) in comparison with control without the addition of the antimicro-bial agent. After application of composite with silver nanoparticles, the decrease of 68.8% was observed, and finally, after application of composite of silver phosphate nanoparticles, the decrease of 5
