Citation Synthesis of Gold Nanoparticles by Blue-Green Algae Spirulina Platensis / T. Kalabegishvili, A. Faanhof, E. Kirkesali et al. // Nanomaterials: Applications & Properties (NAP-2012) : 2-nd International conference, Alushta, the Crimea, September 17-22, 2012 / Edited by: A.

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.
