Resumo

The effect of the degree of anisotropy (axial ratio) of gold nanoparticles on the structure and conductivity of ring deposits formed on a planar substrate upon evaporation of droplets of aqueous dispersions with different particle number concentrations has been studied. A nontrivial phenomenon of a decrease in the specific conductivity of the deposits with an increase in particle concentration in case of gold nanorods dispersions has been revealed.
