Abstract

The self-organization of monolayer gold nanoparticles (AuNPs) on 3-aminopropyltriethoxysilane (APTES)-functionalized glasssubstrate is reported. The orientation of APTES molecules on glass substrates plays an important role in the interaction betweenAuNPs and APTES molecules on the glass substrates. Different orientations of APTES affect the self-organization of AuNps onAPTES-functionalized glass substrates. The as grown monolayers and films annealed in ultrahigh vacuum and air (600 °C) werestudied by water contact angle measurements, atomic force microscopy, X-ray photoelectron spectroscopy, UV-visible spectroscopyand ultraviolet photoelectron spectroscopy. Results of this study are fundamentally important and also can be applied fordesigning and modelling of surface plasmon resonance based sensor applications.
