摘要：

This paper discusses the influence of gold oxidation on functional properties of gold nanoparticles. Pulsed laser ablation in aqueous media was used for production of partially oxidized gold nanoparticles. This technique ensured a gradual oxidation of gold during laser ablation process. The interaction of gold nanoparticles with silanized glass induced a red-shift of the gold plasmon resonance peak in absorption spectra. An in-depth study of the plasmon-related peak as a function of ablation time gave information about the bonding efficiency of Au nanoparticles to amino-groups. We demonstrated that the gradual oxidation of gold nanoparticles clearly affected their functional properties.
