Abstract |
The synthesis of gold nanoparticles by one of the many popular microorganisms – blue-green algae
Spirulina platensis was studied. The complex of optical and analytical methods was applied for investigation
of experimental samples after exposure to chloroaurate (HAuCl4) solution at different doses and for
different time intervals. To characterize formed gold nanoparticles UV-vis Spectrometry, Transmission
Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Energy-dispersive analysis of X-rays
(EDAX) were used. It was shown that after 1.5 – 2 days of exposure the extracellular formation of nanoparticles
of spherical form and the distribution peak within the interval of 20-30 nm took place. To determine
gold concentrations in the Spirulina platensis biomass neutron activation analysis (NAA) was applied.
