Synthesis of Gold Nanoparticles by Blue-Green Algae Spirulina Platensis

摘要

The synthesis of gold nanoparticles by one of the many popular microorganisms – blue-green algaeudSpirulina platensis was studied. The complex of optical and analytical methods was applied for investigationudof experimental samples after exposure to chloroaurate (HAuCl4) solution at different doses and foruddifferent time intervals. To characterize formed gold nanoparticles UV-vis Spectrometry, TransmissionudElectron Microscopy (TEM), Scanning Electron Microscopy (SEM), Energy-dispersive analysis of X-raysud(EDAX) were used. It was shown that after 1.5 – 2 days of exposure the extracellular formation of nanoparticlesudof spherical form and the distribution peak within the interval of 20-30 nm took place. To determineudgold concentrations in the Spirulina platensis biomass neutron activation analysis (NAA) was applied.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/34969
