Fabrication of a nanoarchitecture made of 2–6 nm Au nanoparticles selectively attached onto patterned SAMs. (A) Schematic of Au nanoparticle/SAMs structure created by AFM inscription, further functionalization of inscribed SAMs pattern with NTS, and selective attachment of Au nanoparticles. (B) The poster, entitled “World Without Weapons”, created by Picasso in 1962. This was translated into an input signal to the conducting AFM tip that inscribes (contact mode, line width ∼30 nm) a corresponding pattern on the top surface of OTS/Si monolayer specimen. (C) AFM topography image after 2–6 nm Au nanoparticles were deposited on amine terminated SAMs pattern, showing nanoscale replica of the poster made of nanoparticles/SAMs. (Reprinted with permission from Reference [91].
