Abstract

Softly, softly: A novel modification strategy for layered chalcogenide nanoparticles (NPs) takes advantage of the chalcophilic affinity of Mn ²⁺. Surface-bound MnO NPs can be selectively bound to the surface of WS₂ nanotubes and functionalized with the fluorescent dopamine derivative NBD at room temperature. The MnO NPs can also be reversibly detached from the chalcogenide surface with excess dopamine at elevated temperatures.
