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 WS 2 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.
