Abstract

An approach based on orthogonal self-assembly strategies for obtaining crosslinked arrays of nanoparticles with controlled morphologies was presented. In this approach double-stranded DNA served as a template for the interaction of psoralene functionalized gold nanoparticles, which were subsequently crosslinked to the template via a photochemical transformation. The CdSe nanoparticles modified with reactive vinylbenzene functionalities assembled at the oil/water interface and subsequent heating afforded robust, extended nanoparticle sheets. The approach was basically used for producing complex one and two dimensional (2D) nanoparticle morphologies in a controlled fashion and achieving mild crosslinking conditions.
