چکیده انگلیسی
The adsorption properties of sensitive films formed by gold nanoparticles, dropped from solutions with different nanoparticles content are investigated using mass-sensitive (QCM) sensors. The dependence of surface adsorption capacity on nanoparticles concentration is shown. The decrease of surface concentration of nanoparticles leads to the increase of sensors sensitivity to different alcohols and water. The adsorption character of water (response amplitude and kinetics) substantially differs form that of alcohols. The sensitivity of gold nanoparticles layers to water is more then one order higher then to alcohols. The kinetics of water adsorption runs in two stages.
