Green Synthesis of Gold Nanoparticles using Arabidopsis thaliana and Dunaliella salina Cell Cultures

Аннотация

The ability of the suspension culture of Arabidopsis thaliana cells and Dunaliella salina microalga to reduce gold ions with the formation of nanoparticles is shown. The average diameter of gold nanoparticles obtained using D. salina for synthesis appeared to be less than when using A. thaliana cells: 8 and 25 nm, respectively. Freshly prepared culture media used for growing cells of both dunaliella and arabidopsis did not reduce gold salts with the formation of nanoparticles. After the cells were grown and freed by centrifugation and/or filtration, culture media turned out to be capable of gold reduction.
