SAM’s (Self Assembled Monolayer’s) are formed by modifying the glass surface at different stages using Silanes, Gold Nanoparticles (Au NPs) and mixture of thiols of different functional groups, chain lengths and proportionate. The synthesized intermediate surfaces and SAM’s obtained are characterized for understanding their behavior in terms of physical and chemical heterogeneities. The gold nanoparticles behavior can be observed using the visible spectrum obtained from UV spectro-photometer. The change in chemical heterogeneities are observed by measuring the contact angle using two variant small molecular weight liquids (water and ethylene glycol) on various synthesized intermediate surface
