Selective Nanotrench Filling by One-Pot Electroclick Self-Constructed Nanoparticle Films

Abstract

Integration of nanoparticles (NPs) into nanodevices is a challenge for enhanced sensor development. Using NPs as building blocks, a bottom-up approach based on one-pot morphogen-driven electroclick chemistry is reported to self-construct dense and robust conductive Fe3O4 NP films. Deposited covalent NP assemblies establish an electrical connection between two gold electrodes separated by a 100 nm-wide nanotrench.
