Nanoparticles made of CdSe or Au have been extensively utilized for optical labeling and other nano-optical applications. In this case, one technological challenge can be positioning nanoparticles onto desired locations on solid substrates with a nanometer scale precision. We utilized surface-templated assembly strategy to position Au and CdSe nanoparticles onto specific locations on Au and silicon oxide substrates. In our method, thiol-terminated self-assembled monolayer (e.g. MPTMS) patterns are utilized to capture nanoparticles from the solution, while methyl-terminated SAM (e.g. 1-octadecanethiol) patterns are utilized to avoid any unwanted assembly of nanoparticles. We also explored the possibility of assembling fluorescent nanoparticles onto 3D structures such as AFM tip for nano-optical applications.
